Value Collection 581321PR Hex Socket Cap Screw 10-32 Unf

Product Description

The VALUE COLLECTION 581321PR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and equipment maintenance. It features a 10-32 UNF thread size and a 3-1/4 inch length under head, providing ample thread engagement in moderate-depth tapped holes. The 5/32 inch hex drive socket accepts a standard Allen wrench for installation and removal. Constructed from alloy steel with a black oxide coating, this cap screw delivers solid tensile strength and mild corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for industrial and trade applications.

This cap screw is suited for use in machine maintenance, equipment assembly, HVAC component mounting, electrical enclosure work, and general mechanical service where a 10-32 UNF thread is specified. The black oxide finish reduces surface friction and provides light rust inhibition in dry or low-moisture environments. The partially threaded shank allows for clamping force concentration at the joint, which is appropriate for bolted connections requiring controlled preload. Sold in multiples of 10 per order.

Key Features

• 10-32 UNF thread size, partially threaded shank for controlled clamping
• 3-1/4 inch length under head for deep fastening applications
• 5/32 inch hex socket drive compatible with standard Allen wrenches
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide coating provides mild corrosion resistance and reduced galling
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 10-32 UNF hex socket cap screw for use in any application specifying ASME/ANSI B18.3 or ASTM A574 fasteners with a 5/32 inch Allen drive.

Installation Notes

Install using a calibrated 5/32 inch hex key or Allen driver; do not use an undersized or worn key as it may strip the socket. Ensure the tapped hole is clean and free of debris before threading to avoid cross-threading or galling. Alloy steel fasteners in black oxide finish are not rated for outdoor or high-moisture exposure without additional protective treatment. Follow the applicable torque specification for 10-32 UNF alloy steel fasteners per your equipment or assembly documentation.
