Value Collection 580655PR Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 580655PR is a 1/4-20 flat head slotted machine screw designed for general-purpose fastening applications. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw features a 1-3/4 inch overall length and unified national coarse (UNC) threading. The flat head profile sits flush with or below the surface of the work material, making it well suited for assemblies where a low-profile fastener is required. Installers in mechanical, HVAC, electrical, and light industrial trades commonly use this screw type for panel attachment, equipment mounting, and general metal or wood fastening tasks.

This machine screw is appropriate for light-duty residential and commercial applications where a standard UNC 1/4-20 thread pattern is specified. It is sold in a minimum order quantity of 100 pieces per order, with each package containing 1 unit. Typical installation scenarios include control panel assembly, equipment enclosures, sheet metal work, and general maintenance tasks requiring a flush-mount fastener.

Key Features

• 1/4-20 UNC thread pattern for wide compatibility with standard tapped holes and nuts
• Flat head profile allows flush or countersunk installation in mating material
• Slotted drive accepts standard flat-blade screwdrivers for installation and removal
• Grade 2 steel construction provides adequate strength for light-duty fastening
• Zinc finish offers basic corrosion resistance for general indoor and sheltered use
• 1-3/4 inch overall length measured from tip to top of head

Compatibility

Designed as a standard UNC 1/4-20 machine screw suitable for use with any tapped hole, threaded insert, or hex nut conforming to the 1/4-20 unified national coarse thread standard.

Installation Notes

Install using a flat-blade screwdriver matched to the slotted drive width to avoid cam-out and head damage. For countersunk applications, ensure the receiving material is properly countersunk to accept the flat head profile before driving the fastener. Do not exceed the torque capacity appropriate for Grade 2 steel at this thread size to avoid fastener failure. Follow applicable mechanical or electrical codes when using machine screws in panel or enclosure assemblies.
