Robertson S2 Insert Bit, 1/4″ Hex Drive, 1-15/16″ – Eclipse S2X1-15/16

Eclipse S2X1-15/16 — Robertson S2 Insert Bit, 1/4″ Hex Drive, 1-15/16″

The Eclipse S2X1-15/16 is a Robertson (square) S2 insert bit designed for accurate, repeatable fastening in production, service, and field environments. Its 1-15/16″ overall length and 1/4″ hex shank deliver the reach and control technicians need while fitting standard magnetic and quick-change bit holders. The S2 square tip provides positive engagement with Robertson screws to reduce cam-out, protect fastener heads, and transfer torque efficiently. Constructed from S-2 tool steel with a hardness of HRC 59–61, it stands up to repetitive driving and daily use in power drivers and hand tools. The insert-bit form factor streamlines changeovers, helping installers keep pace on busy jobs. Its balanced length makes it easy to work inside junction boxes, AV racks, and tight cabinetry without sacrificing access. For integrators, OEM buyers, and MRO teams, this bit supports consistent results across assembly lines, service trucks, and maintenance benches.

Use it anywhere Robertson fasteners are specified, from low-voltage and security installs to fixture assembly and general electronics work. Available for local pickup at our Mesa, Arizona counter and fast shipping throughout Phoenix, Chandler, Tempe, Gilbert, Scottsdale, Glendale, and nationwide.
