Simpson Strong-Tie MTWS48-5.5 MTWS® 5-7/16 in. x 47-5/8 in. 7-Gauge Mass Timber Washer Strap

Simpson Strong-Tie® tested and load-rated tension straps and fasteners are designed to minimize cost and maximize speed and precision — while providing the strength, versatility and reliability you depend on. The MTWS48 strap utilizes MTW45-8 washers and Strong-Drive® SDCF Timber-CF (SDCF) fully-threaded countersunk-head screws. The combination provides a tension strap with high strength and stiffness that can be used in a variety of CLT diaphragm and wall applications. The MTWS48 is a 7-gauge high-capacity strap specifically designed to carry tension across a CLT floor or wall panel joint. The MTWS48 can also be used to attach CLT panels to steel attachment points when paired with a welded connection (designed by others).

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
