About the 96977A128 Press-Fit Drill Bushing, 2mm ID Head
McMaster-Carr catalogue number 96977A128 is a headed press-fit drill bushing in the metric range: a 2 mm bore in a 5 mm outside diameter, 7 mm long overall, which leaves a 1.5 mm wall around the bore. Press-fit drill bushings, also called jig bushings, are pressed straight into a hole in a jig or fixture plate and guide the cutting tool so that hole position and squareness repeat from part to part. What characterises this size is how little of the plate it occupies: a 5 mm outside diameter lets bushing centres sit close together, so several guided holes can be grouped in a small area of the plate. The 7 mm body gives about three and a half bore diameters of guide length behind the cutting edge, and the head is a flange that seats on the plate face and fixes how far the bushing enters. The bore takes 2 mm drills.

Typical applications
A 2 mm guided hole belongs to instrument and light-assembly work: pilot holes for small screws, dowel positions in thin brackets and repeat holes in sheet material. Fixtures using bushings this small are typical of bench jigs for avionics trays, sensor and antenna mounts and small UAV structures. The compact outside diameter also suits crowded hole patterns where a larger bushing body would not fit between centres.
