Stewart Fastener J0648MRCZ Round Head Machine Screw 6-32 X 3

Product Description

The STEWART FASTENER J0648MRCZ is a round head combination-drive machine screw in a 6-32 thread size with a 3-inch length, sold in a package of 100. The 6-32 designation indicates a number 6 diameter with 32 threads per inch, a standard unified coarse thread used widely in mechanical assemblies. The combination drive head accepts both slotted and Phillips drivers, giving installers flexibility on the job. This screw is a general-purpose fastener suited for joining sheet metal panels, enclosures, and equipment components across HVAC, electrical, and plumbing service work.

These machine screws are commonly used in light to medium-duty fastening applications where a consistent thread form and a low-profile round head are required. Typical uses include securing control panels, junction box covers, access doors, and equipment mounting brackets. The 100-count package format makes this screw practical for service technicians and shop stock alike, reducing the need for frequent reorders on high-turnover fastener sizes.

Installation Notes

Installation does not require specialized tools beyond a Phillips or slotted screwdriver or the corresponding power bit. Always verify that the receiving hole is properly tapped to 6-32 before driving the screw to avoid cross-threading. De-energize any electrical equipment before fastening panels or enclosures. Follow applicable NEC or equipment manufacturer guidelines when securing electrical enclosure hardware.
