Stewart Fastener J3732MRCZ Round Head Machine Screw

Product Description

The STEWART FASTENER J3732MRCZ is a round head machine screw sized 3/8-16 x 2 inches, designed for secure mechanical fastening in trade and industrial applications. The 3/8-16 designation refers to a 3/8-inch nominal diameter with 16 threads per inch, a coarse-thread specification widely used in HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies. Licensed tradespeople rely on this screw type for panel attachment, bracket mounting, and component fastening where a low-profile round head and reliable thread engagement are required.

This machine screw is suited for residential and light commercial applications across multiple trades. HVAC technicians commonly use this fastener size when securing access panels, motor mounts, and sheet metal components. Plumbers and electricians also encounter this thread size on equipment enclosures and structural brackets. Sold individually, this screw is available packaged in jars of 50 units, allowing technicians to stock a working supply on the truck or in the shop.

Key Features

• 3/8-16 coarse thread for broad compatibility with standard tapped holes and nuts
• 2-inch length provides adequate grip depth for panel and bracket fastening
• Round head profile distributes clamping load and sits flush above the fastened surface
• Machine screw design requires a pre-tapped hole or mating nut for installation
• Available in jars of 50 for convenient bulk storage and job-site access

Compatibility

Designed as a standard 3/8-16 coarse-thread machine screw for use wherever this thread specification and a 2-inch length are required in mechanical, HVAC, plumbing, or electrical assemblies.

Installation Notes

Installation requires a pre-tapped hole or a suitable 3/8-16 hex nut and washer. Use the correct driver bit or wrench to avoid cam-out or head damage. Ensure mating threads are clean and free of debris before driving. Follow applicable equipment manufacturer torque guidelines and relevant code requirements for the trade application.
