Compare pitch, length, bearing surface and head clearance with the original hardware. Use a correctly fitting T30 tool. For brake or other safety-critical connections, use the equipment maker's approved fastener and tightening procedure. To prevent tool cam-out and drive stripping on high-torque assemblies, consult our Titanium Fastener Drive Stripping & Failure Guide.
