Value Collection R52001183 Hex Head Bolt 3/8-16 Grade 2

Product Description

The VALUE COLLECTION R52001183 is a Grade 2 steel hex head bolt designed for general-purpose fastening in light to medium-duty structural and mechanical applications. With a 3/8-16 UNC thread size and a 3-inch length under head, this partially threaded fastener is supplied with a hot-dipped galvanized finish that provides corrosion resistance in outdoor, wet, or moderately harsh environments. The 9/16-inch hex drive is compatible with standard wrenches and sockets. Manufactured to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 standards, this bolt meets established dimensional and mechanical requirements for inch-series hex fasteners. It is a practical choice for contractors, maintenance technicians, and tradespeople working across HVAC, plumbing, electrical, and general construction disciplines.

This bolt is suited for residential and light commercial applications where a standard galvanized Grade 2 fastener is specified. Typical use cases include mounting equipment to framing, securing brackets and supports, and general structural assembly where full corrosion protection is not required but weather resistance is beneficial. The partial threading leaves a smooth shank near the head, which is appropriate for fastening through clearance holes in stacked materials. This fastener is sold in multiples of 50 units per order.

Key Features

Compatibility

Designed as a standard inch-series hex head bolt for use wherever a 3/8-16 UNC, Grade 2 galvanized fastener meeting ANSI/ASME B18.2.1 or ANSI/ASME B18.2.2 specifications is required.

Installation Notes

Install using a 9/16-inch wrench or socket driver. Follow applicable building codes and equipment manufacturer specifications for fastener torque and engagement requirements. Inspect the galvanized coating before installation and avoid using fasteners with damaged coating in highly corrosive environments. When fastening into steel or treated lumber, ensure thread engagement meets minimum depth requirements per applicable standards.
