Stock through bolt and washer to attach the buttstock to a Sharps Borchardt action. The bolt is 7" long, 7/16"-14 threads. 5/8" slotted hex head. NOTE! These are longer than the original 5.25" bolt, which makes it easier to reach the bolt from the back of the stock. If you are getting a new stock from us it can be drilled for this bolt, but if you have an original stock you will need a spacer to use this bolt.
