The Midwest Fastener SaberDrive 52532 Lag Screw is engineered for high‑performance fastening in modern construction and structural wood applications. Designed with professional‑grade features such as a large round washer head, advanced corrosion‑resistant coatings, and a slip‑free Star Drive, this screw delivers exceptional holding power while simplifying installation.

Its durable steel construction, paired with SaberDrive’s specialized exterior‑grade XL1500 or Platinum‑level coating, ensures long‑term reliability even in demanding indoor or outdoor environments. Whether you're securing framing components, mounting heavy fixtures, or assembling structural assemblies, this versatile lag screw provides the strength, stability, and ease of use that contractors and builders rely on every day.

Key Features

• Strong, durable steel construction designed for high‑load fastening in structural and general wood applications.
• 5/16" diameter with 2‑1/2" length—ideal for medium‑depth penetration while maintaining robust holding strength.
• Round washer head provides a large bearing surface, improving pull‑through resistance and distributing load more evenly.
• T‑30 Star Drive reduces cam‑out, delivers stronger bit engagement, and offers smoother, slip‑free driving.
• Partial thread design maximizes clamping strength, drawing materials tightly together during installation.
• Type‑17 self‑drilling point minimizes wood splitting and eliminates the need for pre‑drilling in most wood types.
• Tan XL1500 or Platinum protective coating provides enhanced corrosion resistance for exterior or treated lumber use.
• Engineered for professional and DIY use, offering both high strength and straightforward installation.
• Consistent performance in structural fastening tasks, designed to meet the demands of construction‑grade applications.
