Value Collection 580619PR 1/4-20 X 5/8 in Flat Head Slotted Machine

Product Description

The VALUE COLLECTION 580619PR is a 1/4-20 x 5/8 inch overall length flat head 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 slotted drive and a flat head profile that sits flush with or below the mating surface when fully seated. The 1/4-20 thread is Unified National Coarse (UNC), making it compatible with standard tapped holes and nuts of that designation. This fastener is a staple in mechanical assembly, panel mounting, and equipment maintenance across trade and industrial environments.

This machine screw is suited for light to medium-duty fastening in metal, plastic, and wood assemblies where a flush or countersunk finish is required. It is commonly used in HVAC cabinet assembly, electrical enclosure work, plumbing fixture mounting, and general equipment fabrication. The slotted drive is compatible with standard flat-blade screwdrivers and slotted bits. This item is sold in minimum order quantities of 100 pieces per order.

Installation Notes

Install with a flat-blade screwdriver or slotted bit driver sized to match the head recess. When installing into metal panels, ensure the receiving hole is properly countersunk to accept the flat head profile and achieve a flush finish. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners. Follow applicable equipment manufacturer torque guidelines or industry assembly standards when specified.
