Parts Desk Insights

Best Use Case: Use for fastening applications where you want a stainless 18-8 lag screw and a 5/16 x 2-1/2" length for the required bite/hold.

Common Issues: For clean installation, ensure the pilot hole and pre-boring match the material you’re fastening into. If you’re replacing existing fasteners, confirm the old screw length matches 2-1/2" so you achieve proper engagement without bottoming out.
