Custom Stainless Shoulder Captive Screws - Cold Drawn 303 SS

 

These custom stainless shoulder captive screws were manufactured using cold drawn stainless steel bar stock material with a cold headed head and drive.  6-32 thread was incorporated at 5mm +/- 0.5, with a lead in chamfer per print.  The head was made to 8mm in diameter and 1.5mm in height, with the step shoulder measuring 3.6 in diameter by 2mm in length.  The long captive shoulder was set to 2.3mm +0/-0.2 diameter.  Overall length is 31.5mm and the head featured a #2 phillips drive.

Custom Stainless Captive Screws - 10-32 X 3/4 In 18-8 Stainless Steel

These custom stainless captive screws were made using standard off the shelf 10-32 X 3/4" fully threaded socket cap screws in 18-8 stainless steel material.  The .130-.150" diameter shoulder was turned down leaving approximately 1/4" of thread at the end of the screw.  With a relatively loose tolerance on the shoulder diameter this job was a relative breeze and our internal part number is GM-1104-I.
