Value Collection 011283PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The Value Collection 011283PR is a hex socket cap screw designed for precision fastening in applications requiring a compact, high-strength connection. Manufactured from alloy steel with a black oxide finish, this fastener meets ASME/ANSI B18.3 and ASTM A574 standards. It features a 3/8-24 UNF thread size, a 1/2 inch length under head, and a 5/16 inch hex drive socket. The black oxide coating provides moderate corrosion resistance and reduces light reflection in finished assemblies. This screw is fully threaded along its usable length, making it suitable for through-hole and threaded-insert applications in metalworking, machinery, and equipment assembly.

This fastener is used in industrial, mechanical, and fabrication environments where a flush or recessed drive is required. Fully threaded 3/8-24 UNF socket cap screws are commonly installed in jigs, fixtures, machine frames, and equipment housings. The fine thread pitch of the 3/8-24 UNF designation provides higher clamping force and better vibration resistance compared to coarse thread equivalents. These screws are a standard choice for machinists, millwrights, and maintenance technicians working with steel and aluminum assemblies.

Key Features

• 3/8-24 UNF fine thread for high clamping force and vibration resistance
• Fully threaded shaft along the 1/2 inch length under head
• 5/16 inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish for reduced glare and light corrosion protection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for threaded holes or inserts with a 3/8-24 UNF internal thread in metal fabrication, industrial machinery, and mechanical assembly applications.

Installation Notes

Install with a 5/16 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. Follow applicable torque guidelines from ASME or equipment manufacturer documentation for 3/8-24 UNF alloy steel fasteners.
