They work great after prepping them!
My initial impression is that these holdfasts are very well made and the tip angle is perfect. However, before you use them:<br />1- De-grease the shank thoroughly.<br />2- Using 60 or 80 grit sandpaper, do a little "shoe-shine" action on the shank to add some texture to the front and back surfaces, which are what grips the bench.<br />3- Wipe off any metal and grit particles.<br /><br />Once prepped in this manner, they hold really well! I'm very pleased with them, especially for the price.
