Value Collection MP30030 Hex Cap Screw 5/16-18 Grade 5 Zinc 50pk

Product Description

The Value Collection MP30030 is a fully threaded hex head cap screw designed for general mechanical assembly in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable clamping strength and basic corrosion resistance suited to indoor and light-duty outdoor installations. The 5/16-18 UNC thread pattern and 1-1/4-inch length under the head make it a common choice for structural bracketing, equipment mounting, and panel fastening across HVAC, plumbing, and electrical installation work. Sold in packs of 50, this SKU is suited for shops and service fleets that need a reliable stock of standard fasteners on hand.

This cap screw is appropriate for residential and light commercial mechanical work where a fully threaded 5/16-18 UNC inch-series fastener is specified. Typical applications include mounting electrical enclosures, securing HVAC equipment brackets, attaching plumbing support straps, and general structural assembly where Grade 5 steel meets the required load specification. The zinc-plated finish provides a baseline level of corrosion protection suitable for dry or mildly humid indoor environments.

Key Features

• Grade 5 steel construction meets standard strength requirements for mechanical fastening
• Fully threaded shank maximizes thread engagement along the entire 1-1/4-inch length under the head
• 5/16-18 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• Zinc-plated finish provides basic corrosion resistance for indoor and protected installations
• Pack of 50 units supports stocking for service vehicles and shop inventory

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 5/16-18 UNC tapped hole or hex nut meeting the UNC thread standard.

Installation Notes

Installation is performed by general tradespeople using a standard hex wrench, socket, or impact driver fitted with the appropriate drive size. Always verify that the mating nut or tapped hole matches the 5/16-18 UNC thread specification before driving. Do not exceed the rated torque for Grade 5 fasteners at this diameter as referenced in applicable mechanical codes or equipment manufacturer documentation. Inspect the zinc plating for damage before use in any environment where corrosion resistance is critical.
