Value Collection 011303PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011303PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 3/8-24 UNF thread size with a 2.5-inch length under the head and is partially threaded for precise clamping in through-hole and tapped-hole configurations. The 5/16-inch hex drive allows for high-torque installation using a standard Allen or hex key. Manufactured from alloy steel and finished with a black oxide coating, this fastener offers solid corrosion resistance in controlled environments while maintaining the tensile strength required by ASME/ANSI B18.3 and ASTM A574 standards.

This screw is suited for use in precision machining setups, hydraulic component mounting, jig and fixture assembly, and general industrial fabrication where a fine-thread, high-strength socket cap screw is specified. The 3/8-24 UNF fine thread pitch provides tighter thread engagement compared to coarse-thread equivalents, making it appropriate for applications requiring vibration resistance or fine adjustment. It is commonly installed by machinists, millwrights, and mechanical assembly technicians working in manufacturing or maintenance environments.

Key Features

• 3/8-24 UNF fine thread for tight thread engagement and vibration resistance
• 2.5-inch length under head with partial threading for precise clamping
• 5/16-inch hex socket drive for high-torque installation
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides mild corrosion protection in controlled environments
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw compatible with any 3/8-24 UNF tapped hole application requiring a partially threaded alloy steel fastener.

Installation Notes

Install using a calibrated 5/16-inch hex key or Allen driver; ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any equipment before accessing fastener locations on live machinery. Follow applicable ASME or machine builder torque specifications for 3/8-24 alloy steel socket cap screws as outlined in your engineering documentation. Do not exceed rated drive torque, as black oxide does not add lubricity equivalent to a plated or lubricated finish.
