Value Collection MSFI02500430-100BX Flat Head Machine Screw

Product Description

The VALUE COLLECTION MSFI02500430-100BX is a flat head slotted machine screw engineered for general-purpose fastening in metal, wood, and composite assemblies. It features a 1/4-20 unified coarse thread with an overall length of 7/16 inches. The screw is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly humid environments. This fastener meets ANSI B 18.6.7 M, DIN 963, ISO 2009, and JIS B 1101 dimensional standards. Electricians, HVAC installers, plumbers, and general contractors rely on this screw size for panel mounting, bracket attachment, and equipment assembly tasks where a flush or countersunk head profile is required.

The flat head profile allows the fastener to sit flush or below the surface of a countersunk hole, making it well suited for applications where a protruding head would interfere with mating components or covers. Common use cases include securing electrical enclosure panels, mounting HVAC access door latches, attaching pipe hanger brackets, and general sheet metal assembly. This fastener ships in a box of 100 units, making it appropriate for technicians and contractors who need reliable job-site stock for recurring fastening needs across light commercial and residential work.

Key Features

• Slotted drive accepts standard flat-blade screwdrivers and power bits
• Zinc-plated finish provides basic corrosion resistance in indoor and sheltered applications
• Grade 2 steel construction meets ANSI B 18.6.7 M, DIN 963, ISO 2009, and JIS B 1101 standards
• Box quantity of 100 supports job-site stocking and recurring maintenance tasks

Compatibility

Designed as an OEM-style replacement and general-purpose fastener for any application requiring a 1/4-20 coarse-thread flat head slotted screw with an overall length of 7/16 inches.

Installation Notes

Installation is performed by any qualified trade professional using standard hand tools or power drivers fitted with a flat-blade bit. The mating material must be pre-tapped to 1/4-20 or fitted with a compatible threaded insert before driving. For countersunk installations, ensure the receiving hole is chamfered to match the flat head angle so the head seats fully flush. Do not overtighten, as Grade 2 steel has lower tensile strength than Grade 5 or Grade 8 fasteners and is not intended for high-load structural joints.
