Stewart Fastener J1012MRCZ 10-24 X 3/4 in Round Head Machine Screw

Product Description

The STEWART FASTENER J1012MRCZ is a 10-24 x 3/4-inch round head combination drive machine screw with a zinc plated finish. Sold in a jar of 100 pieces, this screw is a standard threaded fastener used across a wide range of trade and light industrial applications. The round head profile sits above the surface of the workpiece, and the combination drive accepts both slotted and Phillips drivers, reducing the chance of a tool mismatch on the job. The zinc plating provides basic corrosion resistance for general indoor and protected outdoor service. Licensed tradespeople and maintenance technicians reach for this size and thread pitch regularly in panel, bracket, and equipment assembly work.

The J1012MRCZ suits residential and light commercial applications where a #10-24 thread pitch is specified. Common use cases include securing electrical enclosure panels, HVAC equipment covers, junction box hardware, plumbing fixture brackets, and general sheet metal or component assembly. The jar-of-100 packaging keeps fasteners organized and accessible on the service vehicle or shop bench. Each screw is sold individually as a single unit from the jar quantity.

Key Features

• 10-24 unified coarse thread pitch for broad compatibility with standard #10-24 tapped holes
• 3/4-inch length suits shallow to mid-depth fastening in panels and brackets
• Round head profile distributes clamping load over a wider surface area
• Combination drive accepts both Phillips and slotted screwdrivers or bits
• Zinc plating provides corrosion resistance for general-service environments
• Packaged in a jar of 100 for organized storage and easy dispensing

Compatibility

Designed for use in any application requiring a standard 10-24 threaded machine screw, including electrical enclosures, HVAC equipment panels, and general mechanical assemblies with 10-24 tapped or nut-fastened connections.

Installation Notes

Installation requires a matching Phillips or slotted screwdriver or bit driver rated for machine screw service. Confirm the receiving hole is tapped to 10-24 or paired with an appropriate nut before driving. Do not overtighten, as the zinc-plated steel head can strip under excessive torque in soft or thin materials. Follow applicable NEC or equipment manufacturer torque and fastener specifications when used in electrical enclosures.
