Product Description

The STEWART FASTENER J3716MRCZ is a 3/8-16 x 1 inch round head machine screw sold in a jar of 100 pieces. This fastener features a coarse 3/8-16 thread pitch and a 1 inch length, making it a standard machine screw used across a wide range of mechanical assembly and equipment maintenance applications. The round head profile provides a low-profile, smooth bearing surface and is driven with a slotted or compatible driver depending on the drive type. Sold as a jar of 100, this format is well suited for bench-stock inventory and field service kits where repeated use of a common fastener size is expected.

This machine screw is appropriate for general mechanical assembly work encountered in HVAC equipment, electrical enclosure mounting, plumbing equipment panels, and pool equipment housings. Tradespeople and maintenance technicians who regularly service or reinstall access panels, brackets, and equipment components will find the jar-of-100 format practical for keeping this size on hand. The 3/8-16 coarse thread is one of the most common unified inch thread sizes in North American equipment manufacturing.
