Q Clamp Assembly Best Practice
Insert the tube fully into the Q Clamp socket before tightening the grubscrew. Use the Allen Key Tool to tighten firmly until the screw contacts the tube surface and the tube is immovable. Do not overtighten. For extended outdoor installations, use stainless steel grubscrews to maintain removability over the installation service life.

Frequently Asked Questions
Q. What is the Allen Key Tool used for with Q Clamps?
A. The Allen Key Tool is sized specifically to fit the grubscrew heads used in Q Clamp fittings. You use it to tighten and loosen Q Clamp grubscrews during assembly, adjustment, and disassembly of tubular structures built with Q Clamps.
Q. What size Allen key do Q Clamps require?
A. Q Clamp grubscrews in the -4 (48.3mm) size range require a specific Allen key size. The Altrad Generation Allen Key Tool is designed to match the grubscrew specification for Size 4 Q Clamps. Using the incorrect key size risks rounding the socket and making the screw irremovable.
Q. Can I use a standard Allen key instead of the Q Clamp Allen Key Tool?
A. You must use an Allen key that exactly matches the grubscrew socket size. A key that is even fractionally too small risks rounding the socket. The Altrad Generation Allen Key Tool is purpose-designed for Q Clamp grubscrews and provides the correct fit for safe installation and removal.
Q. Is the Allen Key Tool available from Altrad Generation?
A. Yes. Altrad Generation stocks the Allen Key Tool for Q Clamp assembly and is alongside the full Q Clamp range. Contact your local branch to confirm stock.
Q. How do I tighten Q Clamp grubscrews correctly?
A. Insert the tube fully into the Q Clamp socket. Tighten the grubscrew with the Allen Key Tool until the screw tip firmly contacts the tube surface and the tube cannot be rotated or pulled out. Do not overtighten to the point of deforming the tube wall, as this weakens the connection and makes disassembly difficult.
