Product Description

The L H Dottie Co RMC384 is a 3/8-16 x 4-inch machine screw with a combination Phillips and slotted drive head. This dual-drive fastener is designed for use in mechanical, electrical, and general trade assembly applications where either a Phillips or flat-blade screwdriver can be used for installation. Sold individually, it is a standard hardware accessory stocked by electricians, HVAC technicians, and plumbers for panel assembly, equipment mounting, and general mechanical fastening tasks requiring a coarse 3/8-16 thread pitch.

This machine screw is suited for residential and light commercial trade applications.

The combination Phillips and slotted drive head adds flexibility when working in tight spaces where only one driver type may be accessible. It is a common hardware accessory carried on service vehicles and in shop inventory.
