Benefits
- 3/8-in hex washer head provides for ultimate torque and higher load-bearing capability in structural wood to wood applications.
- DrawTite™ shank pulls wood members rather than forcing them apart as the fastener drives in and seats.
- Lag-Master™ timber fasteners are mechanically galvanized against corrosion to ASTM B695 Class 55. Grabber’s galvanized coating is ACQ compliant.
- The type 17 point starts and drives into most common wood species without needing to pre-drill..
