#17 x 8" Construction Lag Screws (100 Count) High performance exterior coated Construction Lag Wood Screws are an excellent multipurpose fastener for professional operations & demanding industries. Construction applications include: decking, fencing, roofing, framing, timber frame, post & beam, etc. Construction Lag Screws far exceed standard lag screws in shear strength, compression forces and ease of installation. Our construction lag screws are strong—can be removed and reused. Exterior coating provides an excellent multipurpose fastener for professional operations and demanding industries. #17 x 8" Construction Lag Screws Screw engineering specs: Average shear strength of #17 shank—5294 lbsAverage pull-out strength—2082 lbs (screw pull-out is calculated with a 3" length screw in the wood species: yellow pine.)Triple Coating: 1200-hour corrosion resistance in both ACQ and salt spray conditions. #17 x 8" Construction Lag Screws Many construction fasteners come with a “knurl“, or multiple small protrusions at the top of the threads. This helps ensure that once the end of the threads are reached, the remaining smooth surface of the fastener slides easily, allowing for higher compression forces thanks to its now greatly reduced friction. #17 x 8" Construction Lag Screws Use T40 Driver Bit Modified truss head screw (11/16" head diameter) has better compression that forces deep, wide, sharp screw threads. High quality, heat treated steel Torx/Star drive wood screw head, provides twice the torque of Phillips or square drive screw heads. #17 x 8" Construction Lag Screws Type 17 screw point for quick starts without "walking." 3/8" construction lag screw thread diameter. High quality scr/ew threads cut cleanly and easily through tough materials. The wide and sharp screw threads provide maximum holding power. 14x4" Construction Lag Screws (100 Count) 15x4" Construction Lag Screws (100 Count) 17x7" Construction Lag Screws (100 Count) 15x4" Stainless Steel Construction Lag Screws (100 Count) 9x3" Bronze Star FLAT HEAD Screws (1 Pound) 9x3" Gold Star FLAT HEAD Screws (1 Pound) Add to Cart Buying Options Add to Cart Add to Cart Add to Cart Buying Options Customer Reviews 4.7 out of 5 stars 418 4.7 out of 5 stars 206 4.7 out of 5 stars 80 4.6 out of 5 stars 27 4.7 out of 5 stars 320 — Price $41.95$41.95 — no data $103.95$103.95 $93.95$93.95 $18.95$18.95 — no data Size #14 x 4 Inch #15 x 4 Inches #17 x 7 Inches #15 x 4 Inches #9 x 3 Inches #9 x 3 Inches Type 17 Screw Point ✓ ✓ ✓ ✓ ✓ ✓ Exterior Coated Exterior Coated Exterior Coated Exterior Coated Stainless Steel Exterior Coated Yellow Zinc Usage Decking, Fencing, Roofing, Framing, Timber Frame, Post and Beam and Many More Exterior Applications Decking, Fencing, Roofing, Framing, Timber Frame, Post and Beam and Many More Exterior Applications Decking, Fencing, Roofing, Framing, Timber Frame, Post and Beam and Many More Exterior Applications Chemically Treated Materials, Coastal Areas, Harsh Weather Areas, High Moisture Areas, and Many More Applications Cabinetry, Furniture, Roofing, Framing, and Many More Exterior Applications Cabinetry, Framing, Furniture and many More Wood Applications Screw Count Approximately 100 Screws Approximately 100 Screws Approximately 100 Screws Approximately 100 Screws Approximately 79 Screws Approximately 78 Screws Torx/Star Head Size T25 T30 T40 T30 T25 T25 Easy to Install ✓ ✓ ✓ ✓ ✓ ✓ ACQ and Treated Lumber Compatible ✓ ✓ ✓ ✓ ✓ no data
