When maximum fastening depth, superior holding power, and long‑term corrosion resistance are critical, the Midwest Fastener SaberDrive™ 52536 stands out as a high‑performance structural lag screw built for the toughest applications. Measuring 5/16" in diameter and 5" in length, this fastener is engineered for deep anchoring into dense or layered materials, making it ideal for heavy‑duty structural builds, outdoor installations, and high‑load wood connections.

With a Star Drive head for torque efficiency, a large integrated washer head for increased bearing surface, and an advanced Tan XL1500 exterior coating for weather resistance, the 52536 offers reliable performance from installation through years of service. Its hardened steel body and Type‑17 cutting point ensure clean entry and reduced splitting, even in treated lumber and rugged construction materials.

Key Features

• 5/16" x 5" long‑shank structural lag screw ideal for deep penetration and enhanced load-bearing stability.
• T‑30 Star Drive head minimizes cam‑out and delivers smooth, efficient torque transfer under heavy loads.
• Large washer‑style head increases surface contact for stronger clamping force and reduced pull‑through.
• Type‑17 self‑drilling point reduces the need for pre‑drilling and helps prevent splitting in wood substrates.
• Steel construction ensures consistent strength for demanding structural and exterior applications.
• Tan XL1500 corrosion‑resistant coating for long‑term durability against moisture, wood acids, and outdoor elements.
• Available in multiple packaging counts, commonly 25–30 screws per box depending on retailer.
