The "claw" grips both the blue ones with the aluminum head and the orange ones are for clamping panels together which one has a upward flange, like the roof joint at drip rails or quarter panels to trunk seal.
The W shaped ones for when you are plug welding. I bought them to use with a resistance welder.
All of the clamps came from ebay. The blues are from Cripe. I screwed up with the aluminum headed clamps, only bought 4 should have got more they are now sold out and paid 20 bucks per. They are stout and make the vise grip brand look like something from fisher price, the cheapest I can find them now is 35.
The W ones were 18 and the ones with the swivel pad were 12.
The orange ones I came across a guy selling them for 19 bucks
SHIPPED!!! I bought all 8.
