Value Collection 99219 Hex Head Cap Screw 1-8x3 Grade 8

Product Description

The VALUE COLLECTION 99219 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 1-8 thread pitch with a 3-inch length under head, this fastener is manufactured from Grade 8 steel with an uncoated finish. Grade 8 classification indicates a high tensile strength rating suitable for demanding load applications. The UNC (Unified National Coarse) thread form meets ASME B18.2.1 and SAE J429 standards, confirming dimensional and mechanical compliance for professional use. Sold in a package quantity of 10.

This fastener is suited for use in heavy equipment repair, machinery assembly, structural mounting, and general industrial maintenance where high-strength inch-series hardware is required. The fully threaded body provides maximum thread engagement across the full length under head, making it appropriate for through-bolting applications and assemblies where a nut is used at the opposite end. Tradespeople working in HVAC equipment mounting, plumbing equipment supports, electrical enclosure fabrication, and mechanical service will find this screw applicable across a wide range of fastening tasks.
