Heavy Duty Socket Head Shoulder Screw Kit 4 Pack For Joints
✔️ Thread: 5/16-18, Shoulder: 3/8in, Overall: 1-1/4in, 3/16in Allen

This four piece hardware set includes precision machined shoulder bolts designed specifically for tight fit applications on heavy machinery and weekend fabrication projects. Unlike standard machine screws, these parts feature a smooth unthreaded shaft section that acts as a reliable pivot point or guide pin inside mechanical assemblies.

✅ 5/16-18 thread diameter with secure hold
✅ 3/8 inch solid shoulder for smooth rotation
✅ 1/2 inch shoulder length matches tight spaces
✅ 1-1/4 inch total length fits most linkages

💡 What makes a shoulder bolt handy for rotating machinery components?
These pinned fasteners split the threaded area from the main shaft, keeping things aligned without binding up on heavier rigs.
- The smooth ground shoulder takes less wear against bushings and sliding linkages
- Compact threads clamp secure while leaving plenty of clearance for free pivot movement
- Alloy steel build takes a beating and keeps tight tolerances steady through heavy duty runs
