Hillman Fasteners 190090 Hex Bolt 5/16-18 X 1 in 100 Pack

Product Description

The HILLMAN FASTENERS 190090 is a 5/16-18 x 1 inch hex bolt manufactured from low carbon steel with a coarse thread pattern. Each bolt features a standard hex head designed for use with a wrench or socket driver. Sold in a 100-count box, this fastener is suited for general mechanical assembly, structural connections, and equipment mounting tasks common across HVAC, plumbing, electrical, and general trade work. The coarse thread profile provides reliable engagement in standard tapped holes and nuts of the same thread specification.

This hex bolt is a general-purpose fastener used in residential and light commercial trade applications. It is well suited for equipment mounting brackets, panel assemblies, ductwork supports, and utility connections where a 5/16-18 coarse thread fastener is specified. The 100-count pack format is practical for service vehicles and job-site inventory. Low carbon steel construction makes these bolts appropriate for indoor and dry-environment installations where corrosion resistance is not a primary requirement.

Installation Notes

Installation is performed by hand-starting the bolt into a matching 5/16-18 threaded hole or nut, then tightening with an appropriate wrench or socket driver. Always ensure mating threads are clean and free of debris before installation. Low carbon steel fasteners should not be used in wet or outdoor environments without appropriate corrosion protection measures. Follow applicable mechanical codes and equipment manufacturer torque guidelines for structural or load-bearing connections.
