Value Collection MSCI02500620-100BX 1/4-20 X 5/8 in Screw

Product Description

The VALUE COLLECTION MSCI02500620-100BX is a 1/4-20 x 5/8-inch fillister head machine screw designed for general mechanical assembly work. The fillister head profile sits above the fastened surface, providing a deep slotted drive recess that resists cam-out during installation. Made from Grade 2 steel with a zinc-plated finish, this screw handles standard load-bearing fastening applications where corrosion resistance is a secondary consideration. Threaded to Unified National Coarse (UNC) standards at 1/4-20, it mates reliably with tapped holes and standard hex nuts. These ship in a minimum order quantity of 100 pieces, making them well suited for bench stock and production builds.

This fastener is used across a wide range of residential and light commercial assembly scenarios, including electrical panel work, HVAC equipment assembly, sheet metal enclosures, and general mechanical fabrication. The slotted drive accepts a standard flat-blade screwdriver. Length measurement is taken under the head, confirming a 5/8-inch grip length into the fastened material. Tradespeople stocking hardware kits and technicians performing field service on equipment enclosures will find this screw a standard, reliable choice for 1/4-20 tapped applications.

Key Features

• 1/4-20 UNC thread form for compatibility with standard tapped holes and hex nuts
• Fillister head with deep slotted recess reduces cam-out during installation
• 5/8-inch length measured under the head for consistent grip depth
• Grade 2 steel construction suitable for general-purpose fastening loads
• Zinc-plated finish provides basic corrosion protection in indoor environments
• Sold in lots of 100 pieces for bench stock and production use

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use with pre-tapped holes, threaded inserts, or hex nuts in general mechanical and electrical assembly applications.

Installation Notes

Install using a flat-blade screwdriver matched to the slotted drive width to avoid damaging the recess. De-energize any electrical equipment before fastening components inside live panels or enclosures, in accordance with NFPA 70E lockout/tagout requirements. Do not exceed the load rating of Grade 2 fasteners in high-stress or vibration-prone structural connections. Inspect threads in the mating hole before installation to ensure clean engagement and prevent cross-threading.
