Value Collection MSFI0-502000-100BX 5-40x2 Flat Slotted Screw

Product Description

The VALUE COLLECTION MSFI0-502000-100BX is a 5-40 x 2-inch flat head slotted machine screw manufactured from Grade 2 steel with a zinc-plated finish. It features an overall length of 2 inches and a length under the head of 2 inches, meaning the full shank length is usable below the seating surface. The flat head profile sits flush with or recessed into the mating material when countersunk correctly. The slotted drive accepts a standard flat-blade screwdriver. This fastener is sold in a minimum order quantity of 100 pieces, making it practical for production assembly, maintenance kits, and service stock.

This screw is suited for light-duty mechanical assembly in residential and commercial applications where a flush-mount fastener is required. Typical uses include panel attachment, electrical enclosure assembly, equipment covers, and general sheet metal or thin-stock fastening in HVAC, electrical, plumbing, and related trade work. The 5-40 thread size is common in small-hardware and instrument-grade applications. The zinc plating provides baseline corrosion resistance suitable for indoor and light-exposure environments.

Compatibility

Designed as a standard 5-40 x 2-inch flat head slotted machine screw for general light-duty mechanical assembly where ANSI B 18.6.7 M, DIN 963, ISO 2009, or JIS B 1101 compliant fasteners are specified.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted drive. Countersink the mating material to the correct flat-head angle before driving to ensure flush seating and avoid stress cracking. Do not exceed the rated capacity of the Grade 2 steel by applying torque suited for higher-grade fasteners. Follow applicable mechanical and electrical codes when using these screws in enclosure or equipment assembly work.
