Value Collection 872203PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 872203PR is a hex socket cap screw engineered for use in precision fastening applications across industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a zinc-plated finish, this fastener offers solid corrosion resistance and high tensile strength for demanding service conditions. It carries a 5/16-18 UNC thread specification with a 1/4 inch hex drive and is fully threaded along its 1-inch length under head. Licensed tradespeople, millwrights, maintenance technicians, and field mechanics rely on this type of fastener where a hex key or Allen driver is required and a low-profile cap head is preferred over a standard hex bolt.

This screw is suited for general mechanical assembly, equipment mounting, and structural fastening where a 5/16-18 UNC thread pitch is specified. Fully threaded construction makes it compatible with through-hole applications and short-grip fastening scenarios. The zinc coating provides a baseline level of corrosion protection appropriate for indoor and light-duty outdoor environments. Conformance to ASME B18.8 and ASTM A574 standards ensures dimensional and mechanical consistency expected in professional and OEM applications. Minimum order quantity is 100 pieces; package quantity is 1.

Key Features

• 5/16-18 UNC thread for reliable engagement in standard inch-pattern tapped holes
• Fully threaded along the 1-inch length under head for maximum thread engagement in thin sections
• 1/4 inch hex drive accepts standard hex keys and socket bits
• Alloy steel construction provides high tensile strength for structural and mechanical fastening
• Zinc-plated finish provides corrosion resistance in dry and light-exposure environments
• Meets ASME B18.8 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as a standard ASME B18.8 hex socket cap screw for use in any application requiring a 5/16-18 UNC fully threaded fastener with a 1/4 inch hex drive.

Installation Notes

Installation requires a 1/4 inch hex key or Allen-head socket driver. Ensure mating threads are clean, free of debris, and within tolerance before driving. Apply thread lubricant or thread-locking compound as required by the application specification. Do not exceed the rated torque range for 5/16-18 alloy steel cap screws as defined by the project or equipment manufacturer.
