Spax keeps the product conversation focused on the details buyers and installers actually check: head geometry, coating, thread behavior, point style and installed performance.
Washer head bearing area, aggressive thread bite and repeatable drive feel for timber connections.
Needle-point starts and compact heads for fixtures, trim, cabinetry and shop-built panels.
General construction profiles for installers who move between lumber, sheet goods and hardware.
Coating and thread selections for exterior boards, rail details and weather-exposed fastening.
