Value Collection MP72134 Hex Socket Cap Screw 5/16-18 Unc 50pk

Product Description

The VALUE COLLECTION MP72134 is a 5/16-18 UNC hex socket cap screw designed for general industrial and mechanical fastening applications. It features a 1/4 inch hex drive and measures 1-3/4 inches in length under the head with partial threading. Manufactured from alloy steel with a black oxide finish coating, it meets ASME B18.3 and ASTM A574 standards, making it suitable for moderate-strength fastening tasks where corrosion resistance and a clean appearance are required. This package contains 50 screws. Licensed trades, maintenance technicians, and assembly professionals will find these fasteners appropriate for a wide range of structural and equipment applications.

These hex socket cap screws are commonly used in equipment assembly, machine maintenance, and light structural applications across commercial and industrial settings. The partial threading and 5/16-18 UNC coarse thread pattern suit installations into threaded holes in steel, cast iron, and similar materials. The black oxide coating provides mild corrosion resistance appropriate for indoor or protected environments. These screws work with a standard 1/4 inch hex key or Allen driver, making installation straightforward in tight clearance situations where a hex socket head offers an advantage over a standard bolt head.

Installation Notes

Install using a 1/4 inch hex key or appropriately sized socket driver. Ensure the receiving threads are clean and free of debris before installation. Torque to the value specified by the equipment manufacturer or applicable engineering standard for the application. Black oxide finished fasteners are best suited for dry or lightly oiled indoor environments and are not recommended as the sole corrosion protection in wet or outdoor exposure without additional treatment.
