AGILENT HEX KEY .9MM; LONG ARM METRIC 8710-1977

This item is a metric hex (Allen) key intended for servicing precision Agilent instrumentation; it is used to tighten and loosen small internal hex-head fasteners in chromatography and mass‑spectrometry equipment. Agilent parts catalogs and service parts lists include dedicated hex keys (including sub‑millimeter sizes) as replacement/service tools for maintenance and repair of LC/MS and GC systems. While Agilent documents show a 0.89 mm hex key as a listed tool size used in their service parts, an exact public catalog entry for part number 8710-1977 was not located in the Agilent catalogs and parts lists reviewed; closely related Agilent hex-key part entries (for example 0.8–0.89 mm sizes) are documented in official tool lists.

Key Features:

• Tool type: Metric hex key (Allen key) for hex head fasteners, Agilent service/tool category.
• Nominal size: approximately 0.89 mm (often listed as 0.89 mm in Agilent parts listings for small hex wrenches).
• Style: long‑arm L‑wrench / long reach hex key style (long/straight hex keys documented in Agilent tool listings).

Advantages:

• Enables access to and service of small, recessed hex screws commonly found in Agilent LC/MS and GC assemblies (supports instrument maintenance).
• Long‑arm form provides additional reach and leverage for tight or hard‑to‑access fasteners compared with short keys.
• Matching Agilent tool parts improves compatibility with manufacturer service procedures and replacement‑parts ordering for repairs.
