This is the primary fastening method used when joining two pieces of t-slot aluminum profile. The fastener couples with the taper in the t-slots to create an extremely rigid joint. The tabs on the fastener align the profiles and provide anti-rotational support. The standard fastener is used with our metric profiles: 40, 30, 28 and 20 series as well as our inch profiles: 1.5” and 1” series. Parker’s T-Slot Aluminum Framing materials can create an unlimited variety of machine bases and frames, linear-slide systems, safety guarding, enclosures, worktables, material handling systems, and other industrial or consumer structures.
