Stewart Fastener J1032MRCZ 10-24x2 Round Head Machine Screws Zinc 100

Product Description

The STEWART FASTENER J1032MRCZ is a zinc-plated round head combination drive machine screw sized 10-24 x 2 inches, sold in a jar of 100. The 10-24 thread designation means a No. 10 diameter with 24 threads per inch, a common coarse thread used widely in HVAC panels, electrical enclosures, and general sheet-metal assembly. The combination drive head accepts both a flathead and Phillips driver, giving technicians flexibility in the field. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty applications.

These machine screws are a standard hardware item used across residential and light commercial trade work. HVAC technicians reach for 10-24 fasteners when securing control boards, access panels, and junction box covers. Electricians use them for mounting components inside panels and enclosures. The 2-inch length accommodates stacked materials or thicker gauge steel brackets where shorter fasteners fall short. Buying in a jar of 100 supports ongoing service work without constant restocking.

Key Features

• 10-24 thread pitch — widely compatible with standard tapped holes in HVAC and electrical hardware
• 2-inch length suits thicker assemblies and stacked panel installations
• Round head profile distributes clamping load across the surface
• Combination drive accepts Phillips or flathead screwdrivers
• Zinc plating provides corrosion resistance for indoor service environments
• Jar of 100 units supports high-volume field and shop use

Compatibility

Designed for use in any application requiring a No. 10-24 tapped hole or 10-24 nut, including HVAC panel assemblies, electrical enclosures, junction boxes, and general sheet-metal fabrication.

Installation Notes

De-energize all electrical equipment before fastening or removing screws in live panels or control boxes, following applicable NEC requirements. Use a properly sized Phillips or flathead screwdriver to avoid cam-out and head damage. Do not overtighten into thin sheet metal or plastic standoffs, as 10-24 threads can strip soft base materials. Confirm thread engagement is sufficient for the material stack before final torque.
