This Irwin clamp has a well defined shape that allows me to get into those hard to reach places. The screw movement plunges strongly and straight. The end is strong but flexible under heavy stress when screwing. The apex is well developed, muscular and large compared to others. The tip feels solid and is able to deal with all the bolts on the stem. CONCLUSION: Outstanding screwing action and consistently strong hold. The shaft moves well and the rotating tip is large and well attached to the shaft. easily adapts to any screwdriving situation. The main body is strong and rigid, with a hand-friendly ribbed design that feels good in hand to adjust/reposition when screwing. Good staining will help prevent rust. *****EARN 5 Stars!
