This British-made TENAX female button has a lightly textured, knurled edge that distinguishes it from the smooth No. 31 button. It forms the top part of a TENAX fastening and connects to a compatible male stud.
The button is secured to the material with a suitable TENAX locking ring or nut, tightened using a TENAX fastening key. TENAX fasteners are widely used for heavy duty applications, including marine covers.
This listing is for the knurled button only. Stud, locking ring or nut, and fastening key are sold separately.
