Stewart Fastener J3732CH2Z Hex Head Cap Screw 3/8 X 2 in

Product Description

The STEWART FASTENER J3732CH2Z is a 3/8-16 x 2 inch hex head cap screw manufactured to Grade 2 specifications and finished with a zinc coating for corrosion resistance. This fastener features a standard hex drive head and unified coarse thread (UNC) at 16 threads per inch, making it a widely used general-purpose bolt for light to medium structural and mechanical connections. The zinc plating provides basic protection against rust and oxidation in typical indoor and sheltered outdoor applications. Trade professionals and maintenance technicians across HVAC, plumbing, electrical, and general mechanical service work reach for Grade 2 zinc hex cap screws as a reliable stock fastener for equipment mounting, bracket assembly, and panel attachment.

This cap screw is suited for general fastening applications in residential and light commercial settings. Common uses include securing equipment mounting brackets, attaching access panels, anchoring structural framing components, and general mechanical assembly where high-strength alloy fasteners are not required. Its 3/8-16 UNC thread pattern is compatible with standard 3/8-16 hex nuts, washers, and threaded inserts widely available in the trade.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard hardware
• 2 inch grip length suits medium-depth fastening applications
• Grade 2 specification for general-purpose light to medium load use
