Value Collection R52001158 Thread Cutting Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION R52001158 is a flat-head, Type F thread cutting screw designed for use in metal fastening applications where a self-tapping connection is required. Sized at 3/8-16 UNC with a 3/4-inch overall length, this screw features a No. 4 Phillips drive and a Type F point that cuts threads directly into pre-drilled or punched holes without requiring a separate tap. It is manufactured from AISI 1016-1024 steel and finished with zinc plating for basic corrosion resistance. Trade professionals in HVAC, electrical, and general mechanical assembly rely on this fastener type for sheet metal panels, junction boxes, and equipment enclosures.

This thread cutting screw is suited for light-gauge metal applications in both residential and commercial settings. Common install scenarios include securing access panels on HVAC equipment, fastening electrical enclosure covers, and attaching sheet metal components during equipment fabrication or field repair. The flat head profile sits flush with the mating surface, making it appropriate where a low-profile finish is required. The Phillips drive is compatible with standard No. 4 screwdriver bits and magnetic tip drivers commonly carried by service technicians.

Compatibility

Designed as an OEM-style replacement or general-use thread cutting fastener for light-gauge metal assemblies including HVAC equipment panels, electrical enclosures, and sheet metal fabrications requiring a 3/8-16 UNC flat-head screw.

Installation Notes

Installation is performed by licensed HVAC technicians, electricians, or mechanical assembly professionals. Power down and de-energize any equipment before replacing or installing fasteners on live panels or enclosures. A pre-drilled or punched clearance hole of the appropriate diameter is required for the Type F point to engage and cut threads properly. Follow NEC or applicable local codes when fastening electrical enclosure components.
