"IMSCREWS 1/2"" x 2-1/2"" Heavy-Duty Lag Screws - 304 Stainless Steel (2 PCS)

Professional Grade Structural Strength
The 1/2"" diameter is the heavy-hitter of wood fasteners, providing the highest level of shear resistance for safety-critical joints. These 2.5-inch bolts are the industrial choice for anchoring standard 2x lumber (1.5"" thick) into structural 4x4 or 6x6 posts, creating a foundation that can handle significant weight and lateral force.

Vise-Like Clamping Power
Our partially threaded shank features a smooth upper section that allows the bolt to pull the outer timber tightly against the support structure. By eliminating ""thread-jacking"" or bridging, this design ensures the two wood surfaces are clamped together with maximum tension for a rock-solid, gap-free connection.

304 Stainless Weather Protection
Forged from premium 18-8 (304) stainless steel for elite rust protection in outdoor and humid environments. compatible with ACQ pressure-treated lumber. These screws are designed to prevent structural failure due to corrosion and eliminate unsightly rust streaks on cedar, redwood, or premium deck framing.

FAQ
¡ñ Tools: Fits a standard 3/4"" hex socket or wrench.
¡ñ Pre-drilling: Mandatory for 1/2"" bolts. Use a 5/16"" bit for softwoods or 3/8"" bit for hardwoods to prevent timber splitting while ensuring maximum thread bite.
¡ñ Why 2-1/2"" length? Perfect for passing through 1.5"" thick timber with a deep 1"" thread anchor in the base post for maximum stability.
