Value Collection MP39106 Hex Cap Screw 1/2-13 Grade 8 25pk

Product Description

The VALUE COLLECTION MP39106 is a fully threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and equipment assembly work. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers high tensile strength and corrosion resistance. The 1/2-13 UNC thread profile and 1-1/2 inch length under head make it a common choice in general industrial and trade applications. Sold in packs of 25, it meets ASME B18.2.1 and SAE J429 standards, ensuring dimensional and mechanical conformance.

This hex head cap screw is suited for a wide range of trade and industrial applications including HVAC equipment mounting, electrical enclosure assembly, plumbing fixture bracketing, and general mechanical assembly. The Grade 8 rating indicates high proof load and tensile strength, making it appropriate for bolted joints that require reliable clamping force under vibration or load. The zinc yellow dichromate finish provides a baseline level of corrosion protection in indoor and light outdoor environments.

Installation Notes

Installation should be performed by qualified tradespeople familiar with proper fastener torque procedures for Grade 8 hardware. Always use the appropriate hex socket or wrench to avoid fastener damage. Follow applicable mechanical or structural codes for joint design and bolt preload requirements. Do not mix Grade 8 fasteners with lower-grade nuts or washers, as mismatched hardware can compromise joint integrity.
