About Us

With over 40 years of expe­ri­ence work­ing across mul­ti­ple indus­tries, Clark Fix­tures has become a leader in the qual­i­ty ver­i­fi­ca­tion indus­try. Our focus on qual­i­ty and cus­tomer ser­vice has helped us grow to serve clients around the world.

Global Reach

Today we ser­vice accounts in eleven coun­tries and have mul­ti­ple facil­i­ties to ser­vice our cus­tomers around the world. We par­tic­i­pate in trade shows, speak at var­i­ous sem­i­nars, and pub­lish arti­cles on per­ti­nent issues in indus­try trade publications.


We have the tech­ni­cal acu­men to pro­vide a full-ser­vice solu­tion for all your gage and fix­ture needs, no mat­ter what indus­try you rep­re­sent. With numer­ous qual­i­ty ver­i­fi­ca­tions built into our ISO 9001 cer­ti­fied pro­ce­dure we believe we can pro­vide you with the best in process or final audit check fix­ture available.


The enve­lope tol­er­ance con­cept, whether in a full-con­tour or more open pin style, is the best means to ver­i­fy qual­i­ty. It allows vir­tu­al­ly any per­son with a min­i­mum amount of train­ing to know whether their work is accept­able. When applied at each stage of pro­duc­tion it also assures the ear­ly elim­i­na­tion of defec­tive parts, which elim­i­nates scrap while adding value.


Our fix­tures are made in a CNC envi­ron­ment and machined as one piece, which pro­vides two ben­e­fits: First, the machin­ing tol­er­ance is dis­trib­uted over the entire fix­ture, rather then stack­ing up cumu­la­tive tol­er­ances of many indi­vid­ual blocks. Sec­ond­ly, it pro­vides for a well-con­struct­ed fix­ture that is more accu­rate and can last the entire life of the program.
