Product Description

The L H Dottie Co 5MB38312 is a Grade 5 hex head bolt sized 3/8-16 x 3.5 inches, intended for general mechanical fastening in trade and industrial applications. Grade 5 fasteners meet medium-strength requirements and are commonly specified for equipment mounting, structural bracketing, and general hardware assembly. The 3/8-16 thread designation indicates a 3/8-inch nominal diameter with 16 threads per inch, a coarse-thread profile suited for fast assembly and use in a wide range of ferrous and non-ferrous materials. Licensed tradespeople across HVAC, electrical, and plumbing disciplines routinely use fasteners of this specification for equipment installation and panel mounting.

This bolt is sold individually and is appropriate for residential and light commercial trade work. Typical applications include mounting HVAC equipment frames, securing electrical enclosures, anchoring plumbing support structures, and general hardware assembly where a coarse-thread medium-strength hex bolt is specified. Its 3.5-inch length provides adequate grip range for standard material thicknesses encountered in mechanical room and utility installations.
