The SPAX 1/4 in. x 3 in. PowerLags Hex Lag Screws, available in a 500-pack, are engineered for demanding wood-to-wood structural applications. Manufactured from durable steel and finished with a High Corrosion Resistant (HCR) coating, these lag screws are designed to withstand harsh outdoor environments, including coastal construction and treated lumber installations. The hex head with an integrated washer ensures a secure grip and efficient fastening, while the patented thread serrations eliminate the need for pre-drilling, saving time and effort on the job site. These screws require up to 40% less driving torque, increasing installation speed and reducing user fatigue. Each screw features a fastener length stamp on the head for easy identification and streamlined inspections. SPAX PowerLags are building code listed and load rated under ICC-ES ESR-1782, providing peace of mind for contractors and DIY enthusiasts alike. This pack includes 500 lag screws and a bit, making it ideal for large projects that demand reliability, strength, and rust resistance in every fastener.
