Value Collection 31838 Hex Thread Cutting Screw 1/4-20

Product Description

The VALUE COLLECTION 31838 is a 1/4-20 UNC hex head thread cutting screw designed for fastening into pre-drilled or punched holes in metal, plastics, and similar materials. It features a Type F point, which uses a chip-clearing cutting action to form mating threads on installation without requiring a pre-tapped hole. The screw is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The under-head length is 1/2 inch. This fastener is installed by maintenance technicians, HVAC service pros, electricians, and general tradespeople using a hex driver or wrench.

This screw is suited for light-duty sheet metal assembly, electrical enclosure work, HVAC equipment panels, and similar trade applications where a self-threading fastener is needed in thin metal or rigid substrates. The 1/4-20 UNC thread is a widely used coarse thread standard, making this screw compatible with standard 1/4-20 tooling and hardware. Minimum order quantity is 50 pieces per order.

Key Features

• Type F point cuts threads on installation, eliminating the need for a pre-tapped hole
• 1/4-20 UNC coarse thread for broad tooling compatibility
• Hex head drive accepts standard hex wrenches and hex socket drivers
• Grade 2 steel construction provides adequate strength for light-duty fastening applications
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments
• 1/2 inch under-head length suits thin panel and enclosure applications

Compatibility

Designed as a standard 1/4-20 UNC Type F thread cutting fastener suitable for use in thin metal panels, electrical enclosures, HVAC equipment housings, and similar light-duty trade applications.

Installation Notes

Installation is performed with a hex wrench or hex socket driver sized for a 1/4-20 head. Ensure the substrate material and hole size are appropriate for a Type F thread cutting point before driving. De-energize any electrical equipment before fastening near live components. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners.
