Tenax fasteners are British manufactured and have an enviable reputation as one of the best heavy duty systems available, especially in testing marine conditions where resistance to corrosion is paramount. The female Tenax button is used in conjunction with a male stud. The button is attached to the material with a locking ring or ‘nut’, which is tightened using the special fastening key. The system uses a standard sizing profile with a button diameter of 20mm. All items are available in nickel plate as standard with special finishes available on request. Commonly found on kit cars, classic cars including AC Cobra, MG Midgets, Austin Healey.
