Value Collection MSFI02502750-100BX 1/4-20 Flat Head Slotted Screw

Product Description

The VALUE COLLECTION MSFI02502750-100BX is a 1/4-20 UNC machine screw designed for general fastening applications across mechanical, structural, and fabrication trades. It features a flat head profile with a slotted drive, allowing installation with a standard flat-blade screwdriver. The screw is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly exposed environments. Overall length is 2.75 inches, measured from tip to top of head, with full thread engagement along the length under the head also measuring 2.75 inches. This box contains 100 screws, suitable for production work, service fleets, or shop stock.

These screws are used wherever a 1/4-20 UNC threaded fastener with a countersunk flat head is required. Typical applications include light-gauge steel assemblies, electrical enclosures, HVAC equipment panels, junction boxes, and general shop fabrication. The flat head seats flush with the material surface when installed into a countersunk hole, making it appropriate for applications where a protruding head would interfere with fit or clearance. The zinc plating makes these fasteners suitable for indoor and dry-outdoor use.

Key Features

• 1/4-20 UNC thread form for compatibility with standard tapped holes and nuts
• Flat head profile designed to sit flush when countersunk properly
• Slotted drive accepts standard flat-blade screwdrivers
• Grade 2 steel construction balances strength with cost-effectiveness for general-purpose use
• Zinc-plated finish provides basic corrosion protection in dry environments
• Box of 100 fasteners supports production quantities and bulk service work

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in any pre-tapped or through-hole assembly requiring a countersunk flat head fastener at 2.75 inches overall length.

Installation Notes

Installation should be performed with a flat-blade screwdriver or appropriate bit driver sized to the slotted head. Ensure the receiving hole is properly countersunk to the correct angle before driving the screw flush. De-energize any electrical equipment and shut off relevant systems before replacing or installing fasteners in live assemblies. Do not over-torque; Grade 2 fasteners have lower tensile strength than Grade 5 or Grade 8 hardware and should not be substituted in structural or high-load applications.
