Product Overview

Crown Bolt's Grade 8 cap screws are recommended for high stress applications and are among the strongest grade of fastener available in steel. The grade 8 bolt is compatible with grade 8 nuts and washers of the same thread pitch and diameter. An alternative for using them without nuts is to install them directly into a compatible female threaded hole.

Customer Reviews

1/2 in.-20 tpi x 2-1/2 in. Yellow Zinc Grade 8 Hex Bolt is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Disappointed with what I received The bolts were not as show in the picture. I needed bolts that were threaded completely to the head as shown in the picture. When I received them they were only threaded for the first inch or so.
