Hardgrip
Bralo’s Hardgrip rivet is designed for applications where higher clamping force and strengths are required. Its wide expansion of the blind side causes the load and clamping force to be distributed and therefore makes it suitable for working with hard plastics and thin sheet metal.
SELECT MATERIAL AND HEAD TYPE
Ø
3.2 to 6.4 mm
High tensile and shear strength.
Excellent clamping force values in demanding applications.
Good filling of the drill hole. It compensates for uneven, misaligned or oversized bores and makes it more resistant to vibrations.
Excellent aesthetics on both sides, ideal for thin sheets.
