Value Collection 581316PR Hex Socket Cap Screw 10-32 Unf

Product Description

The VALUE COLLECTION 581316PR is an alloy steel hex socket cap screw designed for secure, high-strength fastening in mechanical and industrial assemblies. It features a 10-32 UNF thread size and measures 2-1/4 inches in length under the head with partial threading along the shank. The drive type is a 5/32-inch internal hex (Allen) socket. A black oxide coating provides moderate corrosion resistance and a consistent dark finish. This fastener meets ASME/ANSI B18.3 and ASTM A574 dimensional and performance standards, making it suitable for precision applications where a flush or low-profile cap head is required.

This screw is commonly used in machinery, tooling fixtures, jigs, equipment enclosures, and general mechanical assemblies where a strong, recessed-drive fastener is needed. The 10-32 UNF fine thread provides good thread engagement and vibration resistance in metal-to-metal applications. Partial threading is typical for through-bolt or clearance-hole configurations. Suitable for use in light industrial, manufacturing, and maintenance environments. Sold individually; minimum order quantity is 100 pieces.

Key Features

• 10-32 UNF fine thread for strong engagement and vibration resistance
• 2-1/4 inch length under head with partial threading along the shank
• 5/32-inch hex socket drive for Allen wrench or hex key installation
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish for moderate corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 socket screw standard

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any threaded 10-32 UNF application requiring a 2-1/4-inch partially threaded alloy steel fastener.

Installation Notes

Install using a 5/32-inch hex key or Allen driver; verify the socket is fully seated before applying torque to avoid cam-out or rounding. Power down and de-energize any equipment before replacing fasteners on live assemblies. Confirm the mating thread is clean and free of debris to achieve full thread engagement. Follow applicable mechanical codes and equipment manufacturer specifications for fastener torque requirements.
