Stewart Fastener J3724CH2Z Grade 2 Hex Cap Bolt 3/8-16 Zinc

Product Description

The STEWART FASTENER J3724CH2Z is a Grade 2 zinc-plated hex cap bolt with a 3/8-16 thread and a 1-1/2-inch length, sold in a jar of 100 fasteners priced per each unit. These bolts are standard coarse-thread fasteners used across a broad range of mechanical and structural assembly applications. The zinc plating provides a basic level of corrosion resistance suitable for indoor and sheltered installations. Licensed tradespeople and general contractors reach for Grade 2 hex cap bolts when code or engineering specifications do not require a higher-strength fastener grade.

These bolts are commonly used in light-duty structural connections, equipment mounting, HVAC equipment bases, plumbing fixture supports, electrical panel framing, and general fabrication work. The 3/8-16 coarse thread is one of the most widely called-out fastener sizes in trade work, and the 1-1/2-inch length suits standard framing members, angle iron, and light-gauge steel assemblies. The jar packaging keeps the supply organized on a service truck or at a job site.

Key Features

• Grade 2 classification — appropriate for general-purpose, non-structural light-duty connections
• 3/8-16 unified coarse thread (UNC) for broad tool and nut compatibility
• 1-1/2-inch length suits standard framing and light fabrication applications
• Zinc plating provides basic corrosion resistance for sheltered environments
• Sold individually from a jar of 100, allowing flexible quantity purchasing

Compatibility

Designed as a standard 3/8-16 UNC Grade 2 hex cap bolt compatible with any hex nut, coupling nut, or tapped hole carrying a matching 3/8-16 coarse thread specification.

Installation Notes

Installation requires a standard 9/16-inch hex wrench or socket driver. Always match the bolt grade to the load requirements specified by the engineer or equipment manufacturer — do not substitute Grade 2 fasteners where Grade 5 or Grade 8 is called out. Torque to the assembly or equipment manufacturer's specification. Follow applicable building codes and trade standards when using fasteners in structural or pressure-bearing connections.
