Value Collection 580795PS 5/16-18 X 6 in Flat Head Slotted Screw

Product Description

The VALUE COLLECTION 580795PS is a 5/16-18 x 6 inch overall length machine screw designed for general mechanical fastening applications. It features a flat head profile with a slotted drive, manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance. At 6 inches under the head, this is a full-length threaded fastener built to Unified National Coarse (UNC) thread standards. It is commonly installed by maintenance technicians, pipefitters, millwrights, and general tradespeople requiring a longer-length coarse-thread fastener for structural or equipment assembly work.

This screw is suited for light to medium duty fastening in metal, wood, and plastic assemblies where a countersunk flat head profile is required. The 5/16-18 UNC thread is one of the most common coarse-thread sizes found in industrial, HVAC, plumbing, and electrical panel applications. It is sold in multiples of 10 units minimum. Individual package quantity is 1.

Key Features

• 5/16-18 UNC coarse thread for broad tool and hardware compatibility
• 6-inch overall length with full 6-inch length under head for deep fastening applications
• Flat head profile seats flush with or below the mating surface
• Slotted drive accepts standard flathead screwdrivers
• Grade 2 steel construction meets general-purpose mechanical fastener standards
• Zinc finish provides basic corrosion resistance in dry or mildly humid environments

Compatibility

Designed as a general-purpose UNC machine screw suitable for use in equipment, panel, and structural assemblies requiring a 5/16-18 coarse-thread flat head fastener.

Installation Notes

Install using a flathead screwdriver or slotted bit rated for the 5/16-18 thread size. Ensure the mating material is pre-tapped or fitted with the correct 5/16-18 threaded insert before driving. Apply appropriate thread lubricant or threadlocker based on the application requirements. Do not overtorque, as Grade 2 steel has lower tensile strength than Grade 5 or Grade 8 fasteners.
