Value Collection 581017PR Hex Socket Cap Screw 1-64 Unc

Product Description

The VALUE COLLECTION 581017PR is a hex socket cap screw designed for precision fastening in tight-clearance applications. It features a 1-64 UNC thread size with full threading along a 3/16-inch length under head. The drive is a 5/64-inch internal hex (Allen) socket. Constructed from alloy steel with a black oxide coating, this screw delivers reliable clamping strength and moderate corrosion resistance in a compact, low-profile form factor. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional and mechanical consistency are required. Installation is performed with a 5/64-inch hex key or Allen driver.

This fastener is suited for light-duty mechanical assemblies, instrumentation, electronics enclosures, and precision equipment where a small-diameter, fine-thread cap screw is needed. The 1-64 UNC thread is one of the smallest unified coarse thread sizes and is commonly found in miniature hardware, small motors, control boards, and panel assemblies. Trade mechanics, machine technicians, and equipment assemblers working with compact or delicate assemblies will find this screw appropriate for securing components with limited torque requirements.

Key Features

• 1-64 UNC thread size for precision miniature fastening applications
• Fully threaded along the 3/16-inch length under head for maximum thread engagement
• 5/64-inch internal hex drive for use with standard Allen keys
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1-64 UNC hex socket cap screw per ASME/ANSI B18.3, suitable for use in any application requiring this thread size and head style.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver; use of an incorrect driver size may strip the socket. Ensure mating threads are clean and free of debris before installation. Apply only hand-tight torque appropriate for a number 1 diameter screw, as alloy steel miniature fasteners can be damaged by excessive torque. Confirm thread engagement depth is adequate for the intended load before putting the assembly into service.
