Review on Simpson SDWS22312DBB R50 6 Lobe Washer Powder Coat Structural: A Secure and Long-lasting Construction Solution by Bim Cook

Revainrating 5 out of 5

Amazingly easy to screw in

Use these with STN22-8 washers and they are insanely easy to screw in - they just seem to slide into joists and studs unlike regular lag screws. No splitting in the glued laminated timber and no pre-drilling required.

Pros
  • Bold thread design
