Review on 🔩 S25MG280 Steel Pre-Bulbed Shank: High-Quality Multi-Grip Rivet-Nut with Gold Zinc Finish, 1/4-20 X .020-.280 Grip Range (Pack of 25) by Brian Krump

Direct comparison on flat steel test panel with standard rib panels available at significantly lower prices. Although the material used in these rivets is almost twice as thick as others, a twist test has shown that standard nuts hold better when twisted. When crushed, they form four (4) "wings" that hold them in place. The standard ribbed ones just fit the hole and seem to hold up much better. upset.
