This is a set of four standoffs and eight screws for the Buck 889 Strider. These are parts made for a custom Buck 889 Strider project from several years ago. An example of these on a customized 889 is shown in picture (not included). They are made of precise machined 7075 Aircraft Grade anodized Aluminum and made in Idaho, USA. Choose your color. The threads are 2-56 and will work with the stock Buck screws if you prefer black screws. They measure 0.407" long overall and the step length is 0.208" and the small round end section is 0.122" diameter.
