If you know the exact part number, enter it in the search box. Most part numbers require an MS prefix (MS40S5-2S). If you are unsure of the part number, type the first 3 letters or numbers and put an * after it to broaden your search results. Or try our SITE MAP.
The stud's head diameter determines the stud series. Each stud series is available in either a countersunk (flush) or a round head style. Stud diameters and head styles are specified in the Base Part Number. Studs come in different Total Lengths (blank lengths) which are indicated by the first dash number. The second dash number denotes the maximum total material thickness (TMT, grip length) the stud can accommodate in thousandths of an inch. Each stud blank length can have up to ten (10) second dash numbers, or grip sizes. These dash numbers are stamped in the head of the stud for easy reference. A-Spec fasteners have the least grip range between sizes of any quick release fastener (0.010"). Therefore, it is important to measure accurately when using them.
* Each new stud will require a new cross pin and maybe a new grommet. So be sure to add them before checking out, and don't forget about the installation tools. We keep all of these items in stock to make your project go smoothly. If you have any questions or need additional information, please Contact Us.
