Flap Disc 40 Grit T27 4-1/2 x7/8 MPN:62176

Hex socket drive #4-40 UNC captive screw offers a small form factor at a size of 3/8 inch in length with an under head height suitable for applications where space is restricted or hidden assemblies are being designed preventing foreign object debris interference thus providing an optimal fit into printed circuit boards. This tamper-resistant cap screw is manufactured using high carbon steel making it strong and durable resistant to torque loss when being tightened, offering corrosion resistance with the application of a protective zinc coating or nickel plating to extend its lifespan in challenging environments. Being fully threaded on the stud this screw allows efficient grip onto PCB surfaces and components while ensuring low voltage drop thus avoiding short circuits thus becoming an essential fastener for hardware applications requiring precise, reliable assembly performance.
