A: Hi Henley, thank you for your message. We want to make sure we address your question regarding the washer size for the STB2 1/2" x 5-1/2" Strong-Bolt®2 Wedge Anchor.

If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you. -Stacy
A: Drill bit diameter needs to match that of the wedge anchor. You will need 1/2" diameter bit for 1/2" diameter wedge anchor. A couple of points to consider: 1. Leave some backup material at the bottom of slab, i.e. do not try to drill right through as the drill bit may blow out the bottom of slab due to hammer action. Leave minimum of 2 3/4" back up material. 2. Zinc plated finish does not provide much of corrosion protection. Consider Strong-Bolt wedge anchor in 304 stainless steel finish.
A: The zinc plated carbon steel Strong-Bolt 2 has a low level of corrosion protection and would be for dry, interior conditions. For exterior, please see the Type 304 stainless steel (STB2-505124SS) which provides a high level of corrosion protection or the Type 316 stainless steel (STB2-505126SS) which is for severe conditions.
