Button Head Screw

The Button Head Screw from BERT TRANSMISSIONS (SKU: BER28) is a precision fastener engineered for high-performance transmission assembly and automotive drivetrain applications. As a mechanic working on everything from stock rebuilds to competition gearboxes, you'll recognize this as a critical component in BERT's modular transmission design. Button head screws are favored in transmission work because their low-profile, rounded cap sits flush or slightly recessed, preventing interference with moving internal components while maintaining the structural integrity of critical bearing surfaces and gear carriers.

This fastener's compact design—measuring 1.7 × 0.65 × 3.35 inches with a featherlight 0.02 lbs weight—makes it ideal for applications where space is at a premium and weight savings matter. The button head profile offers superior grip geometry compared to standard hex caps, allowing controlled torque application without marring the fastener or surrounding aluminum or magnesium casings common in modern transmission housings. BERT TRANSMISSIONS' engineering specification ensures these screws meet precise pitch and tensile requirements, critical for maintaining clutch pack clearances and preventing gear rattle during hard acceleration or deceleration cycles.

This button head screw is essential for transmission rebuilders, drag racing shops, and performance enthusiasts doing BERT transmission installs or refreshes. Whether you're assembling a fresh build or resealing an existing gearbox, correct fastener selection prevents case splitting and ensures all internal components remain precisely positioned under load. Stock this hardware alongside your BERT transmission parts to simplify assembly workflow and eliminate trips back to the shop for missing fasteners—professional builders and weekend warriors alike depend on OEM-spec hardware for reliable, leak-free transmission performance.
