PEM has a new product out, their ‘SpotFast’ fasteners. It’s a double-flush rivet, but is press fit like almost everything else they make. They have the additional ability to be used as captive pivots! Interesting; I’ve used custom countersunk semi-tubular rivets for a double flush pivot in the past, and obviously this lower cost solution would be attractive. I recently finished a chassis design that used these; I needed a double flush solution for joining two walls together; I ruled out swaging (almost chose that, but thought it’d be better to reduce the number of second op stations needed), spot welding (chassis is zinc pre-plate), and even the double flush pop rivets (MOQ problems) before settling on these. The chassis already has a lot of other press fit hardware, so this is just one more part to install (3X). Read more over at PEM’s website.
