Value Collection 101706BR Set Screw 1-8x1 Cup Point Grade 8

Product Description

The VALUE COLLECTION 101706BR is a 1-8 x 1 inch cup point set screw manufactured from Grade 8 alloy steel. Set screws are fully threaded fasteners with no head, designed to secure a component such as a collar, gear, or pulley onto a shaft by bearing force directly against the shaft surface. The cup point tip bites into the mating surface to resist rotation and axial movement. This screw is driven with a 9/16 inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. It is used across mechanical assemblies wherever a flush or recessed fastening point is required. Maintenance mechanics, millwrights, and industrial technicians are the typical installers.

This set screw suits general industrial and mechanical applications including shaft-to-hub connections, set collar assemblies, and mechanical drive components. The UNC (Unified National Coarse) thread standard makes it compatible with standard inch-series tapped holes. Its Grade 8 alloy steel construction provides the tensile strength needed in moderate-to-high load applications such as conveyor components, motor shaft collars, and power transmission assemblies.

Key Features

• Cup point tip engages shaft surface for positive grip against rotation and axial displacement
• Grade 8 alloy steel construction for high tensile strength in demanding mechanical applications
• 1-8 UNC thread provides broad compatibility with standard inch-series tapped holes
• 9/16 inch hex drive allows use with standard hex keys and Allen wrenches
• Headless design sits flush or below the mating surface, reducing snag and clearance issues
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard inch-series set screw for any application requiring a 1-8 UNC threaded, headless cup point fastener in a Grade 8 alloy steel material.

Installation Notes

Installation is performed by mechanics and millwrights using a calibrated hex key or Allen wrench of the correct 9/16 inch size. Always ensure the mating tapped hole is clean and free of debris before threading the screw. De-energize and lock out any rotating equipment before tightening or loosening set screws on shaft assemblies. Do not substitute a lower-grade fastener in applications specifying Grade 8 tensile requirements.
