IMSCREWS 1/2"-13 x 2-1/4" Heavy-Duty 304 SS Carriage Bolts (5 PCS)
Substantial Strength for Heavy Structural and Marine Projects The IMSCREWS 1/2" x 2-1/4" carriage bolt is engineered for high-load projects requiring maximum shear resistance. With a robust 1/2-inch diameter and a precise 2.25-inch length, these bolts are the ideal choice for securing industrial brackets, dock hardware, and heavy timber-to-metal connections. The length is perfectly suited for passing through 1.5-inch actual thickness lumber while leaving sufficient thread for a snug, structural connection even with thick plates. Built for longevity, they offer the structural stability required for outdoor pergolas and commercial timber framing.
Superior Durability and Safety-Focused Design Forged from premium 18-8 (304) SS, these fasteners offer superior resistance to rust in coastal or humid environments. The smooth round head creates a clean, low-profile look that reduces snagging hazards, making them a safe choice for playground sets and residential decks. The integrated square neck locks the bolt into place, preventing spinning and allowing for easy, one-sided tightening from the nut side.
