IMSCREWS 3/8 x 1-1/2 Hex Head Lag Screws, 304 Stainless Steel, Fully Threaded Industrial Wood Bolts for Heavy Brackets, 5 pcs

"IMSCREWS 3/8 x 1-1/2 Heavy-Duty Lag Screws - 304 Stainless Steel (5 pcs)

Maximum Shear Strength for Structural Mounting
When 1/4 or 5/16 fasteners aren't enough, these 3/8 diameter bolts deliver industrial-grade stability. Perfectly sized to provide maximum penetration in standard 2x lumber (1.5 actual thickness) without piercing the back. Ideal for mounting heavy-duty casters, steel brackets, or deck hardware.

Fully Threaded for Elite Bite
In shorter 1.5-inch fasteners, thread engagement is critical. Our fully threaded design ensures constant contact from the sharp tip to the hex head. This maximizes surface area in the wood fibers, providing the highest possible pull-out resistance in shallow-depth applications where partial threads would be less effective.

304 Stainless Exterior Defense
Forged from premium 18-8 (304) Stainless Steel for ultimate weather protection. compatible with ACQ pressure-treated lumber. Resists rust in humid environments and prevents unsightly rust streaks on high-value cedar, redwood, or deck framing.

FAQ
¡ñ Tools: Fits a standard 9/16 hex socket or wrench.
¡ñ Pre-drilling: Mandatory for this diameter. Use a 1/4 bit for softwoods or 9/32 bit for hardwoods.
¡ñ Why 3/8 diameter? Provides nearly 50% more shear resistance than 5/16 screws for safety-critical loads.
¡ñ Resilience: Rated for marine, coastal, and high-humidity outdoor use.
