Fein knife bolt 31308111002

Fein Industrial Knife Bolt for Slitting Shear Blade Assemblies This specialized knife bolt is a precision-engineered fastener designed to secure the center blade and cutting bars within the head of FEIN slitting shears. Manufactured from high-tensile, heat-treated steel, the bolt is built to withstand the intense shear forces and constant vibrations generated during high-speed metal fabrication. Its specific thread pitch and shoulder geometry are designed to maintain a consistent clamping force, which is critical for ensuring the precise gap alignment required for burr-free, warp-free cutting. By providing a stable pivot or anchor point for the cutting components, this bolt prevents blade wandering and excessive wear on the tool's internal drive mechanism. It serves as an essential hardware component for routine maintenance or blade replacements, ensuring the tool continues to operate at factory-standard tolerances in demanding HVAC, roofing, and industrial environments.
