Value Collection 3112FPP 5/16-18 Unc Thread Cutting Screw

Product Description

The VALUE COLLECTION 3112FPP is a 5/16-18 UNC thread cutting screw designed for use in metal fastening applications where threads must be formed during installation. This pan head fastener features a Type F point, which cuts into unthreaded material to create mating threads without a pre-tapped hole. Made from 1016-1024 steel with a zinc-plated finish for corrosion resistance, the 3112FPP measures 3/4 inches in length under the head and accepts a No. 4 Phillips drive. It is suited for mechanical assembly work performed by electricians, HVAC technicians, sheet metal workers, and general trade installers working with metal substrates.

This screw is commonly used in light-gauge sheet metal assemblies, electrical enclosures, HVAC equipment panels, and similar metal-to-metal or metal-to-plastic fastening scenarios. The pan head profile provides a low-profile clamping surface appropriate for thin stock and formed sheet metal. Its zinc plating makes it suitable for indoor and mildly corrosive environments. This fastener is sold in minimum order quantities of 100 units per package, making it appropriate for production assembly or shop stock replenishment.

Key Features

• 5/16-18 UNC thread size with Type F thread cutting point eliminates the need for a pre-tapped hole
• Pan head profile with No. 4 Phillips drive for standard installation tooling
• 1016-1024 steel construction meets AISI 1016 material standards
• Zinc-plated finish provides corrosion resistance for indoor and light-duty applications
• 3/4 inches length under head suits light-gauge metal panel fastening
• Conforms to ASME B18.6.3, ASME B18.6.4, and SAE J933 dimensional standards

Compatibility

Designed as an OEM-style replacement or production fastener for light-gauge metal assemblies requiring a 5/16-18 UNC thread cutting screw with a pan head and Type F point.

Installation Notes

Installation is performed using a No. 4 Phillips bit with a power driver or hand screwdriver set to appropriate torque to avoid stripping the formed threads. Ensure the base material gauge is compatible with a 5/16-18 thread cutting application before driving. No pre-tapping is required, but a pilot hole sized for thread cutting engagement is recommended per the fastener manufacturer guidance for the specific substrate material. Power down any equipment panels before accessing enclosures during installation.
