Value Collection MSFI03700500-050BX Machine Screw 3/8-16

Product Description

The VALUE COLLECTION MSFI03700500-050BX is a 3/8-16 x 1/2 inch flat head slotted machine screw manufactured from Grade 2 steel with a zinc-plated finish. The flat head profile sits flush with the mating surface when fully driven, making it well suited for applications where a low-profile fastener is required. The slotted drive accepts a standard flat-blade screwdriver. The unified national coarse (UNC) thread form is the most common inch-series thread standard used in North American mechanical assembly. These screws ship in a minimum quantity of 50 per order and are packaged as a single unit. Electricians, HVAC technicians, plumbers, and general mechanical contractors will encounter this fastener size in panel mounting, equipment enclosures, and structural brackets.

This fastener is used in a wide range of light-duty to medium-duty mechanical assembly applications across residential and commercial trade work. The 3/8-16 UNC thread is a standard coarse-thread size found in steel plate, tapped brackets, and threaded inserts in electrical enclosures, HVAC equipment frames, plumbing support hardware, and general structural assemblies. The overall length of 1/2 inch suits thin-stock applications where thread engagement depth is limited. No washer is included with this fastener.

Installation Notes

Installation requires a flat-blade screwdriver or slotted bit sized for a 3/8 inch head. Confirm the mating material is tapped or fitted with a threaded insert to the 3/8-16 UNC specification before driving. Do not exceed the torque capacity of Grade 2 steel fasteners in high-load or vibration-critical joints. Power down or de-energize any electrical enclosure before installing fasteners in or adjacent to live panels, per NEC requirements.
