Stahlwille SW40aDL 11/32" Long Bi-Hex Socket, 1/4" Drive, 50 mm
Available
The Stahlwille 40aDL is the long version of the 1/4" drive inch bi-hex socket, 50 mm long in every size from 5/32 to 9/16" (manufacturer-stated).
Stahlwille's datasheets call this series the long version, and its 2017 brochure lists it as extra deep. The bi-hex (double hexagon, 12-point) profile carries Stahlwille's AS-Drive (Anti-Slip Drive) form, which the maker says transmits high forces to the flats of nuts and bolts without damaging them. The sockets are HPQ steel, chrome-plated, and Stahlwille specifies hand operation only. The range is listed to ASME B 107.1 / Fed. Spec. GGG-W-641 / SAE AS 954-E (manufacturer-stated).

Selecting the right option
Choose the 40aDL when reach is the problem and the fastener is an inch size. The standard-length Stahlwille 40aD 1/4" Drive Bi-Hex Sockets is 23 mm long and suits open fasteners. For metric sizes at the same 50 mm length see the Stahlwille 40DL 1/4" Drive Long Bi-Hex Sockets.
