Overview

The NSi Industries JBLS48 Hexagon Lag Bolt is a precision-engineered fastening solution engineered for structural wood-to-wood, wood-to-metal, and heavy-duty construction applications. Manufactured from high-strength steel with a zinc chromate finish, this lag bolt delivers superior corrosion resistance and long-term durability in outdoor and industrial environments. The 3/8-inch diameter and 4-1/2-inch length provide robust shear and tensile strength for load-bearing connections, while the right-hand thread ensures efficient installation with standard tools. The hexagon head allows for secure tightening using sockets or wrenches, eliminating cam-out and slippage common with Phillips or slotted fasteners. Packaged in quantities of 50, the JBLS48 is ideal for bulk procurement on construction sites, manufacturing floors, and DIY projects requiring reliable, repeatable fastening. Compatible with standard 3/8-inch hex sockets and wrenches, this lag bolt meets industrial-grade performance standards for professional tradespeople and contractors. The zinc chromate coating provides a protective barrier against rust and oxidation, extending service life in humid, coastal, or chemically treated wood environments. Unlike generic lag bolts, the JBLS48 is produced in the USA by NSi Industries, ensuring consistent quality and traceability for critical applications.
