Value Collection -40232-1 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION -40232-1 is a hex socket cap screw designed for precision fastening in mechanical, industrial, and trade applications. Sized at 5/16-24 UNF with a 1-3/4 inch length under head, this screw is partially threaded and driven with a 1/4 inch hex key. The alloy steel construction provides high tensile strength suitable for demanding clamping and assembly tasks. A black oxide finish adds corrosion resistance and reduces surface reflectivity. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for load-bearing mechanical connections where dimensional accuracy and material strength are required.

This screw is used in residential, commercial, and industrial mechanical assemblies where a recessed drive fastener is preferred for flush or countersunk installation. Common applications include HVAC equipment assembly, machinery mounting, pump and motor housings, and general metal fabrication. The fine UNF thread pitch makes it suitable for thinner materials and applications requiring finer adjustment or higher thread engagement strength. This part is sold individually with a minimum order quantity of 50 units.

Key Features

• 5/16-24 UNF fine thread for higher thread engagement in thinner stock
• 1-3/4 inch length under head with partial threading for controlled clamping
• 1/4 inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and low-glare surface
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw for use in any application requiring ASME/ANSI B18.3 compliant fasteners with a 1/4 inch hex drive and alloy steel construction.

Installation Notes

Installation is performed with a 1/4 inch hex key or Allen driver; an L-key, T-handle, or socket-bit driver is recommended for proper torque application. Ensure mating threads are clean and free of debris before installation. Do not use impact drivers without a torque-limiting attachment, as overtightening can damage the socket recess or strip fine UNF threads. Fastener replacement or installation in structural or pressure-bearing assemblies should follow applicable engineering standards and manufacturer specifications.
