With the ongoing demands of size and weight reduction of electrical assemblies, PCBs and avionics equipment, Clarendon Specialty Fasteners have increased its SEMS screw, pre-assembled screw and washers, to include a micro sized range.
Manufactured in the UK against strict AS9100 practice using fully traceable materials from the UK, Europe or the US, SEMS screws by Clarendon offer a significant reduction in Foreign Object Debris (FOD) risk. There’s also a reduction in production time, improved ease of assembly, 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 its online SEMS Configurator tool, that includes custom options. To complement this, 1.6mm diameter SEMS are now available as part of Clarendon’s 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,” states Spencer Wills, sales director for the defence market. “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.”
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.
