SPAX T-Star Pancake Head HCR PowerLags XF

Experience faster, cleaner structural wood-to-wood connections with SPAX POWERLAGS XF Pancake Head structural screws. Engineered for demanding projects, these innovative fasteners eliminate the need for pre-drilling thanks to SPAX’s advanced 4CUT Point. The razor-sharp tip delivers quick starts, reduced splitting, and smooth penetration for efficient installation in both dimensional lumber and large timbers.

POWERLAGS XF Pancake Head screws feature a 30% lower-profile head that seats flush for a clean, professional finish ideal for applications where appearance matters. The wide bearing surface provides strong clamping force, while the precision-engineered T-Star drive ensures exceptional bit engagement. 

Choose the HCR exterior double barrier coating for long-lasting protection in treated lumber and harsh outdoor environments—perfect for decks, pergolas, gazebos, landscaping timbers, and outdoor structures. Every POWERLAGS XF screw is carefully heat-treated to achieve an ideal balance of strength and ductility for structural reliability.
