Overview

The Minerallac Company 55409 3/8-16 x 1/2" hex bolt is a Grade 5 zinc-plated steel fastener designed for industrial applications requiring reliable mechanical strength and corrosion resistance. This hex head bolt features a 3/8-inch diameter with 16 threads per inch and a 1/2-inch length, fully threaded for maximum engagement. The zinc coating provides moderate corrosion protection in indoor or covered outdoor environments, making it suitable for electrical, construction, and general fabrication projects. Unlike standard bolts, this tap bolt eliminates the need for a nut by threading directly into pre-tapped holes, reducing assembly time and component count. The Grade 5 rating ensures a tensile strength of approximately 120,000 PSI, offering robust performance under moderate loads. Common applications include securing conduit straps, panel boards, junction boxes, and structural assemblies where a flush or semi-flush head is preferred. The UNSPSC code 31161600 classifies this as a hex bolt, ensuring compatibility with standard hardware inventories.
  • Grade 5 zinc-plated steel for strength and corrosion resistance
  • 3/8-16 thread pitch with 1/2" length, fully threaded
  • Hex head design for easy installation with standard tools
  • IMP finish for moderate outdoor/indoor corrosion protection
  • Eliminates need for nuts by threading directly into tapped holes
