Value Collection MSTI02500370-100BX 1/4-20 Truss Head Screw

Product Description

The VALUE COLLECTION MSTI02500370-100BX is a 1/4-20 UNC machine screw with a truss head and slotted drive, sold in a box of 100. Manufactured from Grade 2 steel with a zinc-plated finish, these screws measure 3/8 inches in length under the head. The truss head profile offers a wide, low-profile bearing surface suited for applications where a large clamping area is needed without added height. The zinc plating provides basic corrosion resistance for general indoor and light-duty industrial use. These are standard inch-system fasteners appropriate for mechanical assembly, electrical enclosures, panels, and similar trade applications.

These machine screws are used in a wide range of commercial and industrial assembly tasks where a 1/4-20 UNC thread is specified. The truss head and slotted drive make them a common choice for sheet metal assemblies, enclosure panels, junction boxes, and light structural components. They are installed without a washer, as the wide truss head provides its own bearing surface. The box quantity of 100 suits service shops, contractors, and maintenance operations that keep fastener stock on hand.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• Truss head provides a wide, low-profile clamping surface without a separate washer
• Slotted drive works with standard flat-blade screwdrivers
• Grade 2 steel construction for general-purpose fastening applications
• Zinc-plated finish for basic corrosion resistance in dry and light-duty environments
• Box of 100 units supports bulk service and maintenance inventory

Compatibility

Designed as a general-purpose 1/4-20 UNC machine screw suitable for standard tapped holes and hex nuts in inch-system assemblies across HVAC, electrical, plumbing, and general mechanical applications.

Installation Notes

Installation does not require a washer given the truss head bearing surface. Use a flat-blade screwdriver sized to the slot to avoid cam-out and head damage. Ensure the mating thread or nut is rated for Grade 2 loads before applying torque. De-energize any electrical panel or equipment fully before fastening hardware inside enclosures, following applicable NEC guidelines.
