Buying Guide

Choose the right drive type

Torx/Star (T-Star) and Torx-drive options reduce cam-out and are common across high-rated lag screws, improving torque transfer for heavy-duty fastening

Prioritize corrosion resistance

Look for high-corrosion-resistant (HCR) coatings or ceramic/rust-resistant finishes when selecting screws for exterior or moist environments to extend service life

Match head style to application

Washer-head lag screws provide a larger bearing surface for decking and structural connections, while plain hex heads may be better for recessed or machine-driven installs

Consider pack size and kit value

Bulk packs (hundreds of pieces) can lower per-screw cost for large jobs, while smaller specialty packs suit occasional repairs—compare counts versus price to judge value

Check diameter and length for load needs

Select an appropriate diameter and length—1/4 to 3/8 in diameters and varying lengths are represented—to ensure shear and withdrawal capacity meet your project's structural requirements
