Stewart Fastener J0848MRCZ Round Head Machine Screw 8-32x3

Product Description

The STEWART FASTENER J0848MRCZ is a round head combination drive machine screw in an 8-32 thread size with a 3-inch length. The combination drive accepts both slotted and Phillips drivers, giving technicians flexibility on the job when only one driver type is available. These screws are sold individually but packaged in a jar of 100, making them practical for shop stock or service van inventory. Trade professionals across HVAC, electrical, plumbing, and general mechanical work reach for 8-32 machine screws when fastening panels, brackets, and control components to threaded or tapped metal assemblies.

This fastener is suited for light to medium-duty mechanical assemblies where a round head profile is required to sit above the work surface without countersinking. Common applications include securing electrical enclosure panels, HVAC equipment access covers, control board mounting hardware, and similar sheet metal or machined components that use standard 8-32 threaded holes. The 3-inch length accommodates stacked materials or deeper pass-through applications where shorter screws would not achieve adequate thread engagement.

• 3-inch length suits deeper assemblies and stacked material applications

Compatibility

Designed as a standard 8-32 machine screw suitable for any tapped or threaded metal assembly requiring a round head fastener at 3 inches in length.

Installation Notes

Install using a slotted or Phillips screwdriver or matching bit driver. Ensure the receiving hole is properly tapped to 8-32 before installation to avoid thread damage. Power down electrical equipment and shut off relevant systems before removing or replacing fasteners on live panels or control assemblies. Do not overtighten into thin sheet metal to avoid stripping threads.
