Value Collection 601017PR Cup Point Set Screw 1-64 X 1/4 in

Product Description

The VALUE COLLECTION 601017PR is a cup point set screw designed for secure, friction-based fastening in mechanical assemblies. Made from alloy steel and graded to ASTM F912, this fastener delivers reliable holding strength in applications where a flush or recessed fastening solution is required. The cup point bites into the mating surface for positive retention. Drive is hex type with a 0.035 inch drive size, sized for a 0.028 inch hex key. This screw meets ASME/ANSI B18.3 dimensional standards and carries the ASTM F912 material grade, making it a recognized choice for precision mechanical work.

This set screw is used in light-duty mechanical assemblies where a small-diameter, fine-thread fastener is needed to lock collars, hubs, pulleys, knobs, or shafts in place without a protruding head. The 1-64 UNC thread and 1/4 inch overall length make it well suited for compact components in HVAC equipment, motor assemblies, and similar trade applications. Installation is typically performed by a mechanic or technician using a hex key during equipment assembly or field service.

Key Features

• Cup point geometry bites into mating surface for positive rotational and axial retention
• Alloy steel construction with ASTM F912 material grade for reliable strength in mechanical fastening
• Meets ASME/ANSI B18.3 dimensional standard for hex socket set screws
• 1-64 UNC thread provides fine thread engagement in small-diameter tapped holes
• Hex drive with 0.035 inch drive size accommodates standard hex keys
• Headless design sits flush or below the surface for clearance-sensitive assemblies

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1-64 UNC threaded, 1/4 inch overall length cup point set screw with a hex drive.

Installation Notes

Installation is performed by a qualified mechanic or technician using the correct 0.028 inch hex key to avoid rounding the drive recess. De-energize or shut down any equipment and relieve any load on the shaft or assembly before removing or installing set screws. Do not over-torque small-diameter set screws, as the alloy steel threads can strip in aluminum or soft-material tapped holes. Confirm thread engagement depth before torquing to ensure full holding strength.
