Shoulder Locating Pin with U-Shaped Head – Anti-Rotation Tapered Stepped for Precision Jig & Fixture

Product Content:

A locating pin is only useful if it lands in the same spot every time. That’s the whole point of this one. The shoulder gives you a positive depth stop, the tapered step locks into the bushing with a wedge fit that eliminates play, and the U-shaped head lets you pull it out without prying or damaging the bore. You drop it into the fixture plate, the taper engages, and the part locates off the shoulder. The narrow front section guides the pin into the hole; the wider back section locks it solid. No slop, no rotation, no guessing. We make these from hardened steel and grind the critical diameters so the taper contacts evenly across the full engagement. They’re not pretty, but they’re repeatable to a couple of tenths.

Technical Details:

The Shoulder Locating Pin with U-Shaped Head – Anti-Rotation Tapered Stepped for Precision Jig & Fixture key dimensions on this pin are the two step diameters. The front measures 12.4mm, the rear is 17.5mm, and the overall height sits at 26.44mm. The U-shaped head is milled across the top. The shoulder face is ground square to the pin axis—if that face is off, your workpiece sits crooked. The tapered section between the two diameters is what gives you the anti-rotation feature. As you drive the pin into the bushing, the taper wedges tight, eliminating any rotational movement. The 12.4mm front section guides into the locating hole, and the 17.5mm rear locks into the taper. We harden these to 58-62 HRC and grind the O.D. after heat treat to hold straightness within 0.005mm. The U-shaped head is not just for extraction—it also tells your operator which end goes in the hole.
