Self-Ejecting 1/4-Turn Fasteners, 3/8" Diameter

With our captive quarter-turn Dzus assemblies, you won't have to worry about losing body fasteners. These 3/8" nominal studs have a 3/4" diameter head. This size is popular on vintage cars.

Finding the stud and spring receptacle sizes you need couldn't be easier!
All you need is the total thicknesses of all the panels to be fastened together. That's all!

Just measure the thickness of each panel, and add the thicknesses together. (Be sure to include any space between the panels for rivet heads.)
Find your total thickness in the tables below, and order the stud and the spring indicated.

Total Thickness Stud Spring
0.165" - 0.189" 3022-400 or 3023-400 3024-275
0.190" - 0.214" 3022-400 or 3023-400 3024-250
0.265" - 0.289" 3022-500 or 3023-500 3024-275
0.290" - 0.314" 3022-500 or 3023-500 3024-250
0.365" - 0.389" 3022-600 or 3023-600 3024-275
0.390" - 0.414" 3022-600 or 3023-600 3024-250


Still can't figure it out?
As a quick "cheater" trick, order the shortest spring receptacle (Part No. 3024-250). If the assembly is not tight enough, simply add spacing washers between the spring and the panel. This moves the spring away from the stud assembly, taking up the slack.
