The VALUE COLLECTION 400342PR is a 1/2-20 hex head cap screw machined from 18-8 stainless steel. It measures 2 inches under the head with a 3/4-inch hex drive and follows Unified Fine (UNF) thread standards. The 18-8 stainless steel construction provides solid corrosion resistance in wet, marine, and chemical-exposure environments where carbon steel fasteners would degrade. This screw is installed by mechanical contractors, pipefitters, millwrights, and maintenance technicians wherever a fine-thread hex fastener with moderate corrosion resistance is required.
This fastener is suited for a wide range of light industrial, commercial, and residential mechanical assemblies. Fine thread (UNF) engagement makes it well-suited for applications requiring precise torque control or installation into tapped holes in aluminum, stainless, or thin-wall steel components. Common applications include equipment mounting, flange connections, pump assemblies, and general mechanical fastening where stainless steel is specified by design or code. Sold individually, with a minimum order quantity of 5 pieces.
Designed as a standard 1/2-20 UNF hex head cap screw for use in any application requiring an inch-system fine-thread fastener in that size and grade.
Installation is performed by qualified mechanical or maintenance technicians using a 3/4-inch wrench or socket. Power down and de-energize or depressurize any system before replacing fasteners on live equipment. Do not mix stainless steel fasteners with dissimilar metals in high-galvanic environments without appropriate isolation. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards when tightening.
