Value Collection MSFI0-500370-100BX 5-40 Flat Head Slotted Screw

Product Description

The VALUE COLLECTION MSFI0-500370-100BX is a 5-40 unified coarse thread machine screw with a flat head and slotted drive, sold in a box of 100. Manufactured from Grade 2 steel with a zinc-plated finish, this screw measures 3/8 inches in overall length and is dimensioned to the overall length measurement type with no washer. The zinc coating provides basic corrosion resistance suitable for general indoor and light-duty applications. Fastener technicians, maintenance trades, and assembly professionals use this screw where a countersunk, flush-seating fastener is required in light-gauge steel, plastic, or similar substrates.

This screw is suited for light mechanical assembly, electrical panel work, enclosure fabrication, and general maintenance applications where a 5-40 thread pitch is specified. The flat head profile seats flush with or below the mating surface, making it appropriate for assemblies where protrusion would interfere with fit or clearance. The slotted drive is compatible with standard flathead screwdrivers. It is packaged in a quantity of 100 per box, meeting the minimum order increment for typical shop or field use.

Key Features

• 5-40 unified coarse thread for compatibility with standard 5-40 tapped holes
• Flat countersunk head profile seats flush with the mating surface
• Slotted drive accepts standard flathead screwdrivers
• Grade 2 steel construction for general-purpose mechanical fastening
• Zinc-plated finish for basic corrosion resistance in indoor environments
• Meets ANSI B 18.6.7 M, DIN 963, ISO 2009, and JIS B 1101 fastener standards

Compatibility

Designed as a general-purpose replacement or stock fastener for any application requiring a 5-40 x 3/8 inch flat head slotted machine screw in steel with zinc plating.

Installation Notes

Installation is performed by general maintenance, electrical, or mechanical trades using a standard flathead screwdriver or appropriate bit driver. Ensure the mating hole is properly tapped to 5-40 before installation to avoid cross-threading or fastener damage. Do not overtighten Grade 2 fasteners in soft or thin substrates. Countersink the mating surface to the correct angle to achieve a fully flush seating of the flat head.
