螺母, 螺絲 & 彈簧 for PEC Double Square CLEARANCE

The threads on the screw matched up perfectly with my worn-out 6-inch square, and the spring has a satisfying tension that snaps the blade firmly in place.

Had a PEC double square that was missing its screw for months, and this kit fit perfectly—the threads on the replacement are clean and catch smoothly. It's nice to have the spring as a backup too, even if I didn't need it right away. A simple fix that brought a good tool back to life.

Finally found these tiny spare parts that fit perfectly on my 6-inch double square, the screw threads were exactly the right pitch. Old spring had lost its snap, but this replacement restored that satisfying click when locking the blade.
