The HILLMAN FASTENERS 200360 is a Grade 5 hex cap screw designed for general structural and mechanical fastening applications. Sized at 5/8-11 x 3 inches with coarse thread, this screw is manufactured from heat treated steel for reliable tensile strength in demanding assemblies. Sold in a 25-pack, it suits contractors, maintenance technicians, and trade professionals who need consistent, code-grade hardware on the job. The hex drive head accepts standard wrenches and impact tools. Grade 5 designation meets SAE J429 minimum proof load and tensile strength requirements for medium-carbon steel fasteners.
This hex cap screw is suited for use in structural connections, equipment mounting, and mechanical assemblies across commercial and residential construction, HVAC equipment installation, plumbing system supports, and general mechanical work. The coarse 11-thread-per-inch pitch provides strong thread engagement in steel, cast iron, and similar materials. The 25-pack quantity is practical for installers working on multi-point fastening tasks or stocking a service vehicle.
Designed as a standard 5/8-11 coarse thread hex cap screw suitable for use with matching Grade 5 or Grade 2 hex nuts and washers in structural and mechanical fastening applications.
Installation is performed by qualified tradespeople using standard hand tools or impact drivers with the appropriate hex socket. Always verify thread engagement and torque requirements per the applicable structural or mechanical specification for the assembly. Do not mix Grade 5 fasteners with higher-grade nuts in critical load-bearing connections without confirming compatibility. Follow applicable building codes and equipment manufacturer specifications when using in structural or pressure-bearing assemblies.
