Value Collection 011225P Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 011225P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment fabrication. It features a 5/16-24 UNF thread size with fully threaded construction along a 1/2-inch length under head. The drive is a 1/4-inch internal hex socket, requiring an Allen key or hex driver for installation. Made from alloy steel with a black oxide finish, this fastener delivers reliable clamping force and moderate corrosion resistance in controlled environments. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards, making it suitable for precision fastening work where consistent torque retention is required.

This fastener is used in industrial maintenance, machine assembly, fixture building, and general mechanical repair. The fine 5/16-24 UNF thread pitch provides higher thread engagement per inch compared to coarse thread, making it a preferred choice when vibration resistance or precise torque control is important. Typical applications include securing machine components, mounting brackets, and equipment panels where a low-profile socket drive head is preferred over hex or slotted fasteners. Licensed mechanics, millwrights, and maintenance technicians commonly specify this fastener for production and repair environments.

Key Features

• 5/16-24 UNF fine thread for higher vibration resistance and precise torque control
• Fully threaded shank along the 1/2-inch length under head
• 1/4-inch internal hex socket drive for Allen key or hex driver installation
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application calling for a 5/16-24 UNF fully threaded socket head cap screw with a 1/2-inch length under head.

Installation Notes

A licensed mechanic, millwright, or qualified maintenance technician should verify thread engagement and hole depth before installation. Power down and de-energize any equipment before installing or removing fasteners in live assemblies. Use a calibrated torque wrench with the appropriate 1/4-inch hex bit to achieve consistent clamping force. Do not over-drive; alloy steel fasteners can fail if torqued beyond their rated capacity.
