SSTB16 Anchor Bolt, 5/8 in. x 17-5/8 in.
The SSTB16 is a 5/8 in. x 17-5/8 in. cast-in-place anchor bolt that ties a holdown to the foundation. An offset angle gives more concrete cover and reduces side bursting, and an embedment line stamped on the bolt shows how deep to set it.
Nuts and washers are not included. Add standard nuts, couplers or washers as your holdown requires.
