G-BRA
Bralo’s G-BRA rivet is designed for the most demanding applications, where higher clamping force and high tensile and shear strength are required. Excellent load and clamping force distribution due to the wide expansion of the blind side.
SELECT MATERIAL AND HEAD TYPE
Ø
6.4 mm
Suitable for high tensile and shear strength applications.
Effective mandrel head retention, which transfers excellent clamping force values to the application.
Good filling of the drill hole. It compensates for uneven, misaligned or oversized bores and makes it more resistant to vibrations.
Large support area on the hidden side.
