COMP Cams Super Valve Locks 3/8inThese Steel Super Locks with lash cap recess feature a 10? lock angle and 3 8" valve stem size. They are recommended for all race applications because Super Locks have a wider angle (10?) that better distributes the ever increasing valve spring loads over the retainer than typical 7? locks.

It seems to me like this product is always out of stock. Of the ones I have received and been able to use. They work as advertised and hold an incredible amount of weight. It is very easy to put them on and off, but once they are latched down, you could not remove them by hand without bending the hooks I would like to have a few more boxes to use in my steel building.

Magnet hooks you need!

Size: 4.5", Style: Open

I have been using these all over our shop and helps keep chords, tools and other items off the floor and more organized. I like the ease of the magnet, and it looks like. Built to last. I wish they were not so expensive.

Work great

Relatively strong hooks. The metal I have them on is thin so the magnets arent as steady as I hoped but thats my fault not the hooks. Ample hook space and solidly built

You need these!

Item Package Quantity: 4, Color: Black

These are not really “industrial strength” but they work great and are decent quality, especially for the price. I bought them to use on a sheet metal barn and they hold halters, rakes and other supplies with ease. Out of curiosity I did toss a dewalt drill in one and it held even though I ordered the medium size and the drill didn’t fit super well.
