SEMS screws provide design and manufacturing efficiencies by combining multiple parts, captive washer and screw, into one versatile fastener. This has many benefits which have revolutionised assembly manufacturing processes, particularly in the Aerospace Avionics sector.

Advantages
– Increased productivity by eliminating hand assembly of washers with the screws.
– Permanent assembly ensuring that the washers are not misplaced.
– Safety for the product as there is no chance of a washer being dropped into the assembly.

– One part to inventory, track and assemble.
