The VALUE COLLECTION MP30032 is a Grade 5 steel hex head cap screw sized 5/16-18 x 1-3/4 inches, designed for general mechanical fastening in trade and industrial applications. The partially threaded shank provides a grip area under the head, improving clamping force in bolted joints where full threading is not required. A zinc-plated finish delivers basic corrosion resistance suitable for indoor and light-exposure environments. Each package contains 50 fasteners. The thread form conforms to UNC standards, and the fastener meets ASME B18.2.1 dimensional requirements. Installers working in HVAC, plumbing, electrical, or general mechanical assembly will find this screw a reliable stock item for structural and equipment-mounting connections.
This fastener is used across a wide range of residential and commercial service applications, including equipment mounting, panel assembly, bracket attachment, and structural connections. The 5/16-18 UNC thread is a common size found in HVAC unit frames, electrical enclosures, plumbing supports, and general sheet metal and fabricated-steel assemblies. The partially threaded configuration is suited to applications requiring a smooth shank between mating surfaces. The 50-piece pack is intended for shop stock or field service kits where this size is frequently consumed.
Designed as a standard UNC hex head cap screw suitable for general mechanical, HVAC, plumbing, and electrical equipment fastening applications that require a 5/16-18 thread and 1-3/4 inch grip length.
Installation is performed by licensed tradespeople or qualified mechanics using a standard hex wrench or socket driver sized for a 5/16-18 fastener. De-energize and lock out all electrical equipment and shut off fluid systems before disturbing any mechanical connections. Do not over-torque; refer to applicable ASME, NEC, or equipment manufacturer torque guidelines for the specific joint being fastened. Inspect threads and mating hardware for damage or contamination before assembly.
