Value Collection 0205MSR 2-56 Round Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0205MSR is a 2-56 unified coarse thread machine screw with a round head and slotted drive, intended for light-duty fastening applications in metal, plastic, and composite assemblies. Manufactured from steel with a zinc finish for basic corrosion resistance, this screw measures 5/16 inches in length under head and conforms to ASME B18.6.3 and SAE J82 standards. At 0.00056 pounds per unit, it is suited for precision instrument assembly, electronics enclosures, and small mechanical components where a low-profile round head and simple slotted driver engagement are appropriate. Installation is straightforward and does not require specialized tools beyond a standard flat-blade screwdriver.

This screw is used across a range of light mechanical and electrical assembly applications where a size 2-56 thread form is specified. Typical install scenarios include control panel assembly, small appliance repair, electronic enclosure fastening, and instrumentation work. The slotted round head style provides a clean seating surface without a washer and is well suited for through-hole fastening into tapped holes or with mating nuts in confined spaces. Trade professionals including electricians, HVAC technicians, and electronics assemblers commonly stock this size for service and retrofit work on control boards and enclosures.

Installation Notes

Installation requires a flat-blade screwdriver sized to the slotted head. Verify that the mating hole is tapped to a 2-56 thread specification or that a compatible nut is used before driving the fastener. Avoid overtightening, as the small thread form is susceptible to stripping in soft materials. Inspect threads and seating surfaces for debris or damage before assembly.
