"IMSCREWS 1/4 x 2 Heavy-Duty Lag Screws - 304 Stainless Steel (20 pcs)
Professional Clamping for Structural Joints When you need to pull two pieces of timber tightly together, IMSCREWS 1/4 x 2 Lag Bolts are the engineered solution. The 2-inch length is ideal for joining dimensional lumber or securing heavy brackets to posts, providing significantly higher shear resistance than standard wood screws.
The Advantage of Partial Threading Unlike full-thread screws, our partially threaded design features a smooth upper shank. This allows the screw to spin freely in the outer board, pulling the two components together for a gap-free, rock-solid joint. This vise-like clamping effect is essential for structural integrity and preventing loose connections over time.
304 Stainless Exterior Defense Forged from premium 18-8 (304) Stainless Steel, these screws offer elite weather protection. They are compatible with ACQ pressure-treated lumber, preventing chemical corrosion and unsightly rust streaks on high-value cedar, redwood, or deck framing projects.
Technical FAQ • Tools Required: Fits a standard 7/16 hex socket or wrench. • Pre-drilling: Use a 3/32 bit for softwoods or 5/32 bit for hardwoods to prevent timber splitting. • Why 2 length? Perfect for passing through a 3/4 or 1 outer board with deep 1 + thread engagement into the base post. • Environmental Rating: Ideal for marine, coastal, and high-humidity outdoor use.
ENGINEERED CLAMPING FORCE The partially threaded design allows the smooth shank to pass through the outer board, drawing the two pieces of timber tightly together for a seamless, structural connection.
HEAVY-DUTY ANCHORING The 2-inch length and 1/4-inch diameter provide deep fiber engagement, making these fasteners ideal for heavy-load framing such as deck posts, gazebos, and playground sets.
EXTERIOR STRUCTURAL GRADE Forged from premium 304 (18-8) stainless steel to resist rust and chemical corrosion. Specifically designed for use with ACQ pressure-treated lumber in exposed outdoor projects.
HIGH-TORQUE DRIVE The heavy-duty hex head is built to withstand the high torque required for driving 2-inch bolts. Compatible with standard 7/16 power sockets for a secure, stripped-free installation.
PRECISION INSTALLATION To ensure thread integrity and prevent timber splitting in structural members, pre-drilling a pilot hole (3/16 for softwoods, 7/32 for hardwoods) is required.
