Permanent fastening for brake linings and structural components – The OEM 3501N-105 Rivets are engineered to provide a reliable, vibration‑proof joint for heavy‑duty applications on SINOTRUK HOWO, SHACMAN, and other commercial vehicles. These rivets ensure that brake linings remain securely attached under extreme shear and thermal stress, preventing premature failure and enhancing safety.
Manufactured from high‑carbon cold‑heading steel and heat‑treated to achieve optimal hardness, each rivet delivers consistent strength and ductility. For guaranteed compatibility and long‑term structural integrity, always choose genuine Sinotruk Homan parts.
The 3501N-105 Rivets feature a countersunk head that sits flush with the friction surface, reducing aggressive wear on drums or discs. The zinc‑plated finish provides outstanding corrosion resistance, while the precision‑machined shank ensures a tight fit in OEM holes.
The 3501N-105 Rivets are manufactured using a cold‑heading process that aligns the grain flow along the shank, resulting in superior ductility and resistance to splitting during setting. After heading, the rivets are heat‑treated to achieve a tensile strength of 450‑550 MPa, with a hardness of 85‑95 HRB. This combination of strength and ductility ensures that the rivet expands fully to fill the hole without cracking, creating a permanent, gap‑free joint.
The countersunk head (90° included angle) is designed to sit flush with the brake lining surface, preventing the rivet head from contacting the drum or disc. This reduces wear and eliminates scoring, extending the life of the braking surface. The head is also radiused at the shank transition to eliminate stress risers.
Fleets that use the 3501N-105 report a 95% reduction in loose rivet incidents, and the rivets maintain clamp load even after thousands of brake applications and thermal cycles. The consistent shank diameter (±0.05 mm) ensures a tight fit in OE holes, eliminating the need for oversized rivets or reaming.
Withstands shear loads up to 12 kN per rivet, ensuring brake linings stay attached under emergency braking.
Maintains clamp load at temperatures up to 450°C. No relaxation or loosening after repeated heat cycles.
Yellow zinc plating, 240h salt spray resistance (ASTM B117). Prevents rust and ensures easy disassembly.

The 3501N-105 Rivets are produced using a multi‑step cold‑heading process that ensures uniform grain flow. After heading, the rivets are tumble‑finished to remove any sharp edges and then heat‑treated in a controlled atmosphere furnace. The heat treatment cycle (austenitizing at 880°C, oil quenching, and tempering at 400°C) produces a microstructure of tempered martensite, providing an excellent balance of strength and ductility.
The head and shank are precision‑machined to hold dimensional tolerances of ISO h9 for the shank diameter and ±0.1 mm for head height. The countersunk angle is verified using an optical comparator, ensuring that the head sits flush without protruding above the lining surface.
Every batch is sampled and tested for hardness, shear strength, and head concentricity. A 100% visual inspection detects cracks, burrs, or plating defects. A setting test is performed on a sample of the batch using a calibrated hydraulic press and an actual brake lining/backing plate assembly to verify that the rivet forms a proper tail without cracking.
The zinc plating on 3501N-105 Rivets consists of a 5‑8 µm layer of pure zinc followed by a trivalent chromate conversion coating. This provides 240 hours of salt spray resistance (ASTM B117), ensuring that rivets remain corrosion‑free even in salt‑spray environments such as coastal roads or winter deicing zones.
For extreme applications (e.g., marine or chemical plants), a geometrical coating (Zinc‑flakes) is available on request, providing up to 720 hours of corrosion protection. The standard zinc coating already outperforms plain steel or black oxide finishes by a wide margin.
The coating also acts as a lubricant during setting, reducing the required force and preventing galling of the setting tool.
The 3501N-105 Rivets are designed to be set with standard pneumatic rivet hammers (using a concave snap) or hydraulic presses. The recommended setting force for a 6 mm rivet is 20‑25 kN. The tail should expand to a diameter of 1.3‑1.5 times the original shank diameter, with no visible radial cracks.
These rivets are direct replacements for OEM rivets used on SINOTRUK HOWO, SHACMAN, MAN, and DAF brake shoes. They are also commonly used in clutch disc rebuilding and general sheet metal fabrication where a flush head is required.
When setting, ensure the rivet protrudes through the backing plate by 1.5‑2.0 times the shank diameter before forming. Too little protrusion results in a weak joint; too much can cause the tail to fold improperly.
To correctly set 3501N-105 Rivets, follow these steps: 1) Drill or punch holes in the friction material and backing plate using the correct drill size (shank diameter +0.1 mm). Deburr both sides.
2) Insert the rivet through the lining and backing plate. The head should rest flush with the lining friction surface (countersunk). Ensure the lining is fully seated against the backing plate.
3) Support the head of the rivet with a hardened steel anvil. Use a rivet snap (forming tool) that matches the desired tail shape (bossed or button). For brake linings, a button head tail is typical.
4) Apply a single, steady stroke with a pneumatic rivet gun or hydraulic press. The force must be sufficient to expand the tail to at least 1.3x shank diameter.
5) Inspect the set rivet: no cracks in the tail, no gap between the lining and backing plate, and the head fully seated in the countersink.
6) Repeat for all rivet locations. Torque test a sample rivet if possible – it should resist a tensile pull of at least 3 kN without pulling through.
During brake or clutch inspections, visually check the 3501N-105 Rivets for signs of loosening. Loose rivets will allow relative movement between the lining and backing plate, often indicated by fretting dust around the head. Press on the lining near the rivet; any movement means the rivet is loose.
If any rivet is found loose, the entire lining must be removed, holes inspected for elongation, and new rivets installed. Never reuse a rivet – the tail work‑hardens during setting and will not hold properly a second time.
Corrosion around the rivet head (white or red rust) indicates that the zinc coating has been damaged. Replace the rivet and consider using a brass or stainless steel rivet for the replacement.
Each batch of 3501N-105 Rivets is tested in an ISO 17025 accredited lab. Tests include: (1) Tensile strength (per ASTM E8), (2) Double‑shear strength, (3) Hardness (Rockwell B), (4) Head concentricity and countersink angle, (5) Salt spray resistance (ASTM B117, 240h).
(6) Setting test: ten rivets are set into a standard test coupon and then inspected for cracks and pull‑out force. (7) Microstructure examination (grain flow, decarburization depth). The rivets meet ISO 1891, DIN 660, and ECE R90 standards. A certificate of conformance is provided with each shipment.
The manufacturing facility is IATF 16949 certified, ensuring consistent quality for automotive safety‑critical applications.
A Chinese brake lining manufacturer switched to the 3501N-105 Rivets for their heavy‑duty truck line. After producing 80,000 lining sets, they reported zero field failures due to rivet loosening, compared to a 0.7% failure rate with the previous supplier. The consistent head‑to‑shank concentricity reduced setting tool wear by 50%.
An Australian mining fleet operating 100 HOWO trucks used 3501N-105 rivets to rebuild brake shoes in‑house. The rivets remained tight even after severe brake temperatures (measured at 500°C on the drum), eliminating rattling and premature shoe replacement. The fleet saved 45,000 AUD in new shoe purchases annually.
Each lot of 3501N-105 Rivets is supplied in a sealed plastic bag with a desiccant, placed inside a cardboard box. Boxes contain 100, 500, or 1000 rivets, with foam dividers to prevent damage.
A tamper‑evident hologram sticker with the SINOTRUK Homan logo is affixed to the box. A QR code leads to the authenticity verification portal. Counterfeit rivets often have inconsistent head geometry, weaker steel, or lacking plating. Genuine rivets have a distinctive yellow‑zinc appearance and a smooth head finish.
Always purchase from authorized distributors. The genuine 3501N-105 rivets come with a 12‑month warranty against material defects.
Summary: The SINOTRUK Homan Rivets (OEM 3501N-105) deliver high shear strength, thermal stability, and corrosion resistance for critical fastening applications. Upgrade your brake lining or structural assemblies with genuine OEM rivets – the trusted choice for permanent, vibration‑proof joints.
