Value Collection MSTI02502250-100BX 1/4-20 Truss Screw

Product Description

The VALUE COLLECTION MSTI02502250-100BX is a 1/4-20 truss head machine screw with a slotted drive, manufactured from Grade 2 steel with a zinc finish. The truss head profile provides a wide, low-profile bearing surface useful in thin-material and sheet-metal applications. At 2-1/4 inches length under head, this fastener suits medium-depth clamping and assembly work. Sold in a box of 100, this screw meets ASME B18.6.3 dimensional standards and is suitable for general mechanical assembly in HVAC panels, electrical enclosures, junction boxes, and light structural work where a corrosion-resistant zinc coating is adequate.

This screw is a standard inch-series fastener used across residential and light commercial trade work. Electricians, HVAC technicians, and sheet-metal fabricators commonly use truss head slotted machine screws when attaching panels, cover plates, or cabinet components where head protrusion must be minimized and a standard slotted driver is on hand. The 1/4-20 thread is one of the most common coarse-thread sizes in North American trade applications, making this screw a practical bulk stock item for service vans, panel shops, and installation crews.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts
• Truss head profile delivers a wide bearing surface with low overall head height
• Slotted drive works with standard flat-blade screwdrivers and bits
• Grade 2 steel construction meets ASME B18.6.3 dimensional and strength requirements
• Zinc finish provides basic corrosion resistance for indoor and protected outdoor use
• Box quantity of 100 suited for bulk stocking and repetitive-assembly work

Compatibility

Designed for use in any application requiring a 1/4-20 coarse-thread machine screw with a truss head and slotted drive, conforming to ASME B18.6.3.

Installation Notes

Installation does not require specialized tools beyond a flat-blade screwdriver or bit of the appropriate width and thickness for the slotted head. Ensure the mating tapped hole or nut is the correct 1/4-20 thread specification before driving. Do not overtighten Grade 2 steel fasteners in soft substrates such as aluminum or plastic, as the material grade has lower proof-load ratings than Grade 5 or Grade 8 hardware. Confirm thread engagement depth meets the requirements of the assembly drawing or applicable code before final torque.
