Value Collection SBFI02503000-050BX 1/4-20 X 3 in Flat Head Screw

Product Description

The VALUE COLLECTION SBFI02503000-050BX is a 1/4-20 x 3-inch flat head slotted machine screw manufactured from Grade 2 steel with a zinc-plated finish. The flat head profile sits flush with or below the mating surface when countersunk, making it well-suited for assemblies where a low-profile fastener is required. The slotted drive accepts a standard flat-blade screwdriver. The unified coarse thread (UNC) pattern provides reliable engagement in standard tapped holes and threaded inserts. This screw is sold in a minimum order quantity of 50 pieces per box, making it practical for production, maintenance stock, or service work requiring consistent fastener supply.

This machine screw is used across a wide range of trade and light industrial applications including HVAC equipment panels, electrical enclosures, plumbing fixture brackets, and general mechanical assemblies. The 1/4-20 UNC thread is one of the most common fastener sizes in North American equipment, and the 3-inch length suits applications requiring deeper thread engagement or fastening through thicker material stacks. Grade 2 steel with zinc plating provides adequate corrosion resistance for indoor and light-duty service environments. Licensed tradespeople and maintenance technicians installing or servicing equipment panels, covers, and mounting hardware will find this screw appropriate for general-purpose fastening tasks.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver and is appropriate for any qualified tradesperson or maintenance technician. Ensure the receiving hole is properly tapped to 1/4-20 UNC before driving the screw to avoid cross-threading. Do not overtighten Grade 2 fasteners in soft materials such as aluminum or plastic, as head pull-through or thread strip can result. Power down or de-energize any electrical or mechanical equipment before accessing fastened panels or covers.
