The HMESQK8 is an 8 mm square escutcheon key from the HMEIN Series for HME modular freestanding enclosures. Maintenance teams and facilities staff use it to open doors fitted with the 8 mm square insert.

Standard door hardware on HME enclosures is an escutcheon plate with double bit insert, and a variety of other inserts (and matching keys) are available as alternatives. Once a 8 mm square insert is fitted in place of the standard double bit insert, this key operates it.

The series table pairs the HMESQK8 with the HMESQI8 insert, both described as for escutcheon - 8mm square. Keeping spare keys for each insert profile in use helps avoid access delays during maintenance.

Hammond lists the part as Escutcheon key - 8mm square, short description KEY - 8MM SQUARE. It ships in a bag at 0.2 lbs (0.09 kg) and is REACH and RoHS compliant.

The HMEIN Series lists inserts and matching keys for 7 mm and 8 mm square, 6.5 mm, 7 mm and 8 mm triangle, double bit w/3mm pin and standard double bit profiles, plus a slot coin proof insert and a non-locking insert for the HMEHLKL lift handle, so profiles can be chosen per cabinet. For purchasing and inventory records, the HMESQK8 is identified by UPC 623980051703 and UNSPSC code 39121321.
