Used to replace grub screws that tightened by Allen key. Good quality material (as I discovered when shortening them slightly using a bench belt sander). Photos are an accurate representation of the product.

These thumb screws are as good as they look in the pics. The knurling is deep so you get a good grip.

These are just as pictured and possibly better. Very clean and worked smoothly in my application.
