It holds stainless steel contact seats threaded in place in the inserts. Hardened steel contact points mount in strain gauge frame for positioning in contact seats for measuring strain on dial indicator. The set includes the strain gauge indicator, eight brass inserts, two contact seats, two mounted contact points and a wooden storage case.
