Clarendon expands its SEMS Screw range

With the ongoing demands of size and weight reduction of electrical assemblies, PCBs and avionics equipment, Clarendon Specialty Fasteners has increased its SEMS Screw (Pre-assembled Screw & Washers) to include a micro sized range.

Manufactured in the UK against strict AS9100 practices, using fully traceable material from the UK, Europe or the US, SEMS Screws by Clarendon Specialty Fasteners offer a significant reduction in Foreign Object Debris risk, improve ease of assembly, reduce production time and present an overall cost saving when compared with a standard screw and washer configuration. The current range has an extensive offering of drive styles, head styles, diameters, lengths, finish options and washer configurations, which can be selected using their online SEMS Configurator tool, including custom options.

To complement the current range, 1.6mm diameter SEMS are now available as part of our Micro Range, with additional sizes below the previous 2mm minimum to follow, including Inch size options.

“The ability to offer SEMS Screws under 2mm in diameter is an exciting opportunity to follow the trends of our aerospace, defence and space customers, with the need to reduce size and weight along with offering the added advantage for customers to automate their assembly process knowing they have eliminated the cumbersome task of assembling very small washers to screws, which normally would present a very high risk of FOD,” stated company sales director for the defence market, Spencer Wills.

As with the current range of SEMS Screws, the Micro Range will come with full material and lot traceability, FAI Reports, DFARS compliance and PPAP on request.
