The VALUE COLLECTION -30160-31/2 is a partially threaded hex head cap screw designed for general fastening applications across mechanical, structural, and industrial assembly work. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener meets ASME B18.2.1 standards for dimensional accuracy and head geometry. The 3/4-10 UNC thread and 3.5-inch length under head make it suitable for medium-to-heavy bolted connections where controlled thread engagement and a smooth shank are required. Licensed tradespeople, maintenance mechanics, and contractors keep this size on hand for a wide range of structural and equipment fastening tasks.
This screw is used in residential and commercial construction, equipment mounting, steel fabrication, and mechanical assembly applications where a standard UNC hex head fastener is specified. The partially threaded shank provides a bearing surface that resists lateral shear loads in bolted joints. Sold in a package quantity of 25, this screw suits both job-site use and shop stocking. It is appropriate for use wherever ASME B18.2.1 inch-series hex head fasteners are called out in specifications or hardware schedules.
Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with 3/4-10 UNC nuts, washers, and tapped holes in Grade 5 or equivalent fastener applications.
Installation is performed by mechanics, ironworkers, millwrights, or general contractors using a standard 1-1/8-inch hex wrench or impact socket. Ensure mating threads are clean and free of debris before assembly. Torque to the value specified by the joint designer or applicable structural code for Grade 5 fasteners of this diameter. Do not use this fastener in applications requiring Grade 8 or metric-class hardware unless equivalency has been confirmed by a qualified engineer.
