L H Dottie Co LAG122 Hex Head Lag Screw 1/2 X 2

Product Description

The L H Dottie Co LAG122 is a hex head lag screw sized at 1/2 inch diameter by 2 inches in length. Lag screws in this size range are heavy-duty wood fasteners designed to secure structural members, equipment mounting brackets, and trade-related hardware to wood framing or blocking. The hex head drive style allows installation with a standard socket wrench or impact driver, making it a common choice for HVAC, electrical, and plumbing trades when anchoring equipment supports, strut channels, or junction boxes to wood substrates.

This fastener is suited for residential and light commercial construction and service work. Typical applications include mounting equipment pads, securing duct hangers, anchoring cable trays, or fastening pipe supports to wood joists and studs. The 1/2 inch shank diameter provides substantial holding strength in dimensional lumber and engineered wood products. It is sold individually as a single unit.

Installation Notes

A licensed trade professional or experienced installer should pre-drill a pilot hole sized appropriately for the shank and thread diameter before driving this lag screw to prevent wood splitting. Install using a socket wrench or impact driver rated for the fastener size. Follow applicable building codes, including IBC and local structural fastening requirements, when using lag screws in load-bearing or equipment-support applications. Do not overdrive — seat the fastener until the head bears firmly against the material surface.
