Fasteners for aluminium profiles – T-slot nuts, T-head screws, leveling feet
T-slot nuts and slot screws for the aluminium profile system
Fasteners for aluminium profiles are the screws, nuts and connecting elements used to join slotted profiles into frames, tables, racks and machine guards. T-slot nuts have M5–M8 threads and weigh from 3 g, T-head screws are 12–20 mm long and a leveling screw lets you adjust the height by ±50 mm. The range matches aluminium profiles, most commonly sized 30 × 30 to 45 × 90 mm with an 8 or 10 mm slot.
Which T-slot nuts and slot screws should you choose?
T-slot nuts are inserted into the profile slot and hold the screw of the attached part. The T-slot nut KEA-30 has an M6 thread; the 096H series nuts are available with M5, M6 and M8 threads at 3 g each. Spring nuts KEE-30 (M6, 8.7 g) and KEE-40 (M8, 10.2 g) complete the range for mounting into an already assembled frame. T-head slot screws such as the T-head screw KDA-8x16 (16 mm, 10 g) come in lengths of 12–20 mm; half-round, cylindrical and countersunk head screws in M6 and M8 are also available.
Connectors, clamps and feet for slotted aluminium profiles
Two profiles are joined with the right-angle connectors KCH1-30 and KCH1-40 (20 g), the KCR1-40 clamp made of nickel-plated zinc alloy, the M10 connecting element for 40 × 40 profiles and the M12 × 30 connecting screw for 40 × 40 and 45 × 45 profiles. Further types are available among the joints for aluminium profiles. The structure stands on the leveling screw K-1209E-M8 with a Ø 38 mm base and 87 mm height or on the AD-5508MRM adjustable foot (M8, 55 mm); guard doors are carried by the steel hinge for 40 × 40 profiles.
