Product Description

The L H Dottie Co RMC1412 is a round head combination-drive machine screw measuring 1/4 inch in diameter by 1/2 inch in length, sold in a 100-piece pack. The combination drive accepts both slotted and Phillips drivers, giving technicians flexibility in the field when one driver type is not on hand. Machine screws in this size range are a standard fastener across electrical, HVAC, and light mechanical assembly work. Electricians and HVAC technicians reach for this fastener when securing panels, junction box hardware, and equipment mounting brackets. The 100-piece quantity keeps job site supply steady for high-volume applications.

This fastener is suited for general trade use in residential and light commercial settings. Common applications include securing electrical enclosure hardware, control panel components, and equipment covers. The round head profile sits above the fastened surface, providing a finished appearance and a generous bearing surface without countersinking. Installers working through conduit bodies, terminal blocks, or sheet metal assemblies will find this screw size a frequent fit.
