Value Collection 581232PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 581232PR is a hex socket cap screw designed for applications requiring a compact, high-strength fastener with precise thread engagement. This screw features a 6-40 UNF thread size, a 7/8-inch length under head, and is fully threaded for maximum grip across the fastened joint. Driven with a 7/64-inch hex key, it is manufactured from alloy steel with a black oxide finish for moderate corrosion resistance. Machinists, maintenance technicians, and assembly professionals use this fastener in tight-clearance installations where a low-profile socket-drive head is required.

This screw is suited for precision mechanical assemblies, light industrial equipment, and instrument-grade fixtures where fine-thread engagement and controlled torque loading are priorities. The 6-40 UNF thread provides finer pitch than coarse-thread equivalents, improving resistance to loosening under vibration. It is commonly installed in metal-to-metal applications including brackets, housings, panels, and mechanical subassemblies. Sold in multiples of 100 per order.

Key Features

• 6-40 UNF fully threaded shank for maximum thread engagement in thin or short-depth applications
• 7/8-inch length under head accommodates standard fastening depths in precision assemblies
• 7/64-inch hex drive socket for installation with a standard hex key or Allen driver
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards for mechanical fasteners
• Black oxide finish provides surface protection and reduces light reflection in visible assemblies

Compatibility

Designed as an OEM-style hex socket cap screw suitable for precision mechanical assemblies, instrumentation, and light industrial equipment requiring 6-40 UNF fine-thread fasteners.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 7/64-inch hex key or socket driver. Ensure the receiving thread is clean and free of debris before driving. De-energize or lock out any equipment before fastener replacement in live assemblies. Do not exceed the torque rating of the base material, particularly in aluminum or plastic substrates.
