IS Counterbores

Freer Tool & Supply’s IS counterbores collection is designed for clean, accurate fastener seating in machining, fabrication, and assembly work. Counterbores create flat-bottom recesses that help bolts and socket head cap screws sit properly, improving fit, alignment, and overall assembly quality—especially when you’re working to print and holding tight tolerances.
