Value Collection 0840MCR 8-32 X 2.5 in Round Head Machine Screw

Product Description

The VALUE COLLECTION 0840MCR is a steel machine screw designed for general mechanical assembly applications. It features an 8-32 unified coarse thread, a round head profile, and a combination slotted and Phillips drive for installation flexibility. The screw measures 2.5 inches in length under head and is finished with a zinc plating for basic corrosion resistance. Manufactured to ASME B18.6.3 and SAE J82 standards, this fastener is suited for use in equipment panels, enclosures, and light structural assemblies where a standardized, reliable threaded fastener is required. It is sold in a minimum order quantity of 100 pieces.

This screw is commonly used by HVAC technicians, electricians, and mechanical contractors for securing equipment covers, control boards, junction boxes, and panel components. The round head profile sits flush against the work surface without a washer, making it appropriate for applications where a low-profile finished appearance is acceptable. The combination drive accepts both a standard flat-blade screwdriver and a Phillips driver, which is practical in field service environments where tool availability may vary.

Installation Notes

Install using a Phillips or flat-blade screwdriver sized appropriately for the drive recess to avoid cam-out or slot damage. De-energize all electrical equipment before fastening or removing screws on panels or control assemblies. Do not overtighten into threaded inserts or sheet metal; torque to the assembly manufacturer's specified value. Inspect zinc plating for damage before use in environments with elevated moisture exposure.
