Flange nut
The flange nut works together with the T-bolt: the screw goes into the profile slot, passes through the accessory and the flange nut tightens it from the outside. The wide collar bears firmly on the accessory and the connection is secure and conductive. It is used for the foundation bracket and for fence supports with a foot.
Why choose it
Wide bearing surface
The collar spreads the clamping force over the accessory.
Conductive
Secure, conductive connection, suitable for ESD areas.
Standard wrench
10 mm hex for M6 and 13 mm hex for M8.

For fixing to the profile, T-bolts M8x20 for slot C10 and flange nuts M8; for the floor, the floor anchor. Fit the bracket on the upright, rest it on the ground, drill through the bracket and insert the anchor.
T-bolts M8x20 for slot C10 and flange nuts M8: the screw goes into the upright's slot and the nut clamps the plate. To anchor it to the floor add the floor anchor and the washer.
With the T-bolt for the same slot: M6 in slot C8, M8 in slot C10. The screw is inserted into the slot and turned until it stops; its length depends on the thickness of the accessory. For the foundation bracket, the M8x20 screw is used.
M8x20 T-bolts for slot C10 and M8 flange nuts, to be ordered separately. The 103x103x37 version already includes the fastening material.
On the 45x45 or 45x45L profile with two M8x25 T-bolts and two M8 flange nuts. On the 22.5x45 frame profile with one 5.5x45 self-tapping screw, one M6x20 T-bolt and one flange nut. No machining needed.
With the T-nut, the nut sits in the slot and the screw is driven in from the outside. With the flange nut it is the other way round: the T-bolt sits in the slot and the nut tightens from the outside, with a wide collar bearing on the accessory.
The flange nut: M6 for the screw in slot C8, M8 for the screw in slot C10. The collar rests on the part being fastened.
It is the width of the profile slot and determines which accessories you use. Slot C6 (6 mm) is for 20 series profiles, C8 (8 mm) for the 30 series, C10 (10 mm) for profiles from the 40 series upwards. Nuts, screws, brackets and cover caps are chosen by slot: each accessory's product page shows the right one.
Yes. You can order the full bar or the piece cut to the length you need: we do the cutting ourselves, in our workshop. Each profile's product page shows the maximum bar length and the minimum cut length.
Look at the moments of inertia Ix and Iy: the higher they are, the less the profile deflects under load. For the same section, “L” profiles are lightened and deflect a little more. For long spans or high loads move to a larger section or a tall profile (e.g. 45x90 instead of 45x45). If you send us drawing and loads, we will check the choice.
The T-nut is inserted from the front into the slot, even in an assembled structure, and positions itself when you tighten the screw: it is the standard choice for fixing accessories. The sliding block withstands higher forces, but normally has to be inserted from the profile end before closing the frame; spring versions stay where you put them.
The simplest way is the bracket, which joins two profiles at 90° with screws and nuts in the slot, without machining. For end, T, 45° or three-way connections there are dedicated connectors, some of which require profile machining as stated on their product page.
Yes, for several accessories (for example cover caps, hinges and nuts) there are conductive ESD versions, indicated in the name or variant. Tell us which EPA area you work in and we will confirm the components to use.
On each product page you will find the MGE catalogue pages to download as PDF, with dimensioned drawings and technical data; the Specifications tab shows the data for the variant you have chosen.
Yes. Send us the parts list or a sketch with dimensions: we give you codes, quantities and cut lengths and prepare the kit with profiles already cut and the accessories.
