Value Collection MSFI0-300310-100BX Machine Screw 3-48

Product Description

The VALUE COLLECTION MSFI0-300310-100BX is a 3-48 x 5/16-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 fully driven, making it a standard choice for applications where a low-profile fastener is required. The slotted drive accepts a standard flat-blade screwdriver. The zinc coating provides basic corrosion resistance suitable for indoor and general-purpose use. Sold in a box of 100, this fastener follows Unified National Coarse thread standards and is measured by overall length.

This screw is suited for light-duty mechanical assembly, electrical enclosure work, panel mounting, and general fabrication tasks where a 3-48 UNC thread is specified. The flat head and slotted drive combination is commonly found in electronics, instrumentation housings, and small appliance assembly. Electricians, HVAC technicians, and general tradespeople working with sheet metal panels, junction boxes, or control enclosures will encounter this fastener size in standard hardware applications. The box quantity of 100 supports production runs and service stock replenishment.

Compatibility

Designed as a general-purpose UNC machine screw for any application requiring a 3-48 thread, flat head profile, and slotted drive in a 5/16-inch overall length.

Installation Notes

Use a properly sized flat-blade screwdriver to avoid cam-out and slot damage. For flush or countersunk installation, ensure the mating material is correctly countersunk to match the flat head angle before driving the screw. De-energize any electrical enclosure or panel before fastener work in live equipment. Follow applicable NEC or equipment manufacturer guidelines when securing components inside electrical or control enclosures.
