Big Timber CTX177 #17 x 7" Bronze-Star TRS SKT11 Coated Ledger Screw (250/Box)
The Superior Alternative to the Common Lag Screw Heat treated & hardened, these screws are stronger & more durable than ordinary lag screws. They have deep cutting threads for quick, easy driving & a sharp notched point for exact, quick starting with less “walking”. A built-on round washer head with smooth edges gives a professional finish.
Features
- Unique design reduces need for pre-drilling.
- No additional washer needed!
- Heat treated & hardened.
- Triple Ceramic Coating. 1200-hour corrosion resistance in both ACQ and salt spray conditions. Outstanding abrasion resistance.
- Easily removable & reusable!
- Deep, Wide, Sharp Threads. Provide maximum holding power. Cut cleanly & easily.
- Built-On Round Washer Head. Smooth edges give a neat, finished appearance.
- Star Drive Recess. Twice the torque of Phillips & square drives. Reduces camout and end load. Gives better bit life. Reduces spinning & fastener damage.
- Knurled shank reams hole in board being fastened, reducing drag on shank and driving tool. Makes screw easier & less tiring to drive.
- Spiral notches on threads cut through fibrous materials and greatly reduce the torque needed to drive the screw without affecting holding power.
- Type 17 notched point starts quickly without ‘walking’. Reduces splitting & drive torque requirements by removing wood from the hole as the screw penetrates instead of forcing the wood apart.
