Value Collection 011233P Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 011233P is a fully threaded hex socket cap screw designed for precision fastening in mechanical assemblies, fixtures, and structural connections. The screw features a 5/16-24 UNF thread size and a 1-inch length under head, making it appropriate for fine-thread applications where tighter clamping force and vibration resistance are required. Drive engagement is through a 1/4-inch internal hex (Allen) socket. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength along with moderate corrosion resistance in light-service environments. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.

This cap screw is suited for use in machine tool assemblies, equipment housings, pneumatic and hydraulic fixtures, and other applications where a flush or low-profile fastener head is required. The fine 5/16-24 UNF thread pitch is commonly specified in precision machined components, aerospace-adjacent tooling, and load-bearing mechanical joints where thread engagement accuracy is critical. A licensed machinist, millwright, or mechanical technician typically selects this fastener for its controlled thread tolerance and alloy steel construction.

Key Features

• 5/16-24 UNF fully threaded profile for fine-thread engagement
• 1-inch length under head — fits standard close-tolerance applications
• 1/4-inch hex drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides mild corrosion resistance and reduced light glare
• Meets ASME/ANSI B18.3 dimensional standard for socket head cap screws

Compatibility

Designed as an OEM-style replacement or stock fastener for machinery, fixtures, and mechanical assemblies requiring a 5/16-24 UNF socket head cap screw per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or mechanical technician familiar with fine-thread fastener procedures. Always verify mating thread condition and cleanliness before installation. Use a calibrated torque wrench with the appropriate 1/4-inch hex bit to achieve the specified clamp load without overdriving. Avoid cross-threading by starting the fastener by hand and confirm full thread engagement before applying final torque.
