PowerLags® for Log Homes and Timber Frame Construction

SPAX® PowerLags® bring a new level of fastening efficiency and reliability to log home and timber frame construction. SPAX® patented thread serrations eliminate pre-drilling and dramatically increase installation speed. They are also code-listed and load-rated so that you can be assured of the reliability of the assembly.

The Torx Recess fastener has been an automotive industry standard for many years.

Torx is a patented brand name for a six-pointed drive pattern developed in 1967 by Camcar Textronic. The Generic name Start Drive is commonly used instead of the Trade Marked Torx to identify the six-lobed drive system. Other companies have branded their particular six-lobbed drive system, like Spax, which has a T-Star and T-Star Plus. By design, the six-lobbed drive resists Cam-Out better than Phillips (Phillips is designed to Cam-Out to prevent over-torquing) and slotted head screws.

Sizes are numbered, starting with a "T-" and ranging from 1 to 100. Starting with T-1 to T-10, they step up by increments of 1. From T-10 to T-45, they step up in increments of 5; from T-50 to T100, they step up in increments of 10.

SPAX® T-STAR® The driving surfaces of the T-STAR force application are arranged in the shape of a star and run vertically, simplifying tool insertion and ensuring a firm grip. This force application shape puts an end to the cam-out effect. The contact force during fastening is reduced to a minimum, and high torques can be transmitted to the screw without damaging it or the tool.

SPAX® 4CUT® point: The 4CUT® point enables fastening without pre-drilling (depending on the wood). This is achieved through its special screw tip. The arrow shape pushes through the wood fibers, ensuring a fast grip. This effectively prevents the material from splitting and reduces the insertion moment. For hardwoods, we recommend pre-drilling even when using SPAX with 4CUT.

• No pre-drilling required
• Building code recognized: ICC-ES ESR-1782
• Low-profile, large diameter head designs provide exceptional draw down of even rogue logs
• Deep T-Star drive provides superior bit engagement and allows for easy back-out of the fastener if necessary when the head is countersunk
• Patented thread serrations require up to 40% less driving torque to increase installation speed while helping prevent cracking in logs
• Proprietary coating provides excellent corrosion resistance and prevents staining wet logs
• Fastener length stamp on the head provides convenient identification without measuring and aids on-site inspections
• Job site friendly and weather-resistant packaging
• German engineered thread technology; American made
