This SAE Aerospace Standard (AS) covers high strength thin wall (commercial) sockets, universal sockets, box wrenches and torque adaptors which possess the strength, clearances, and internal wrenching design so configured that, when mated with bi-hexagonal fasteners conforming to the requirements of AS870 for inch sizes and ISO 4095 for metric sizes, they shall transmit torque to the fastener without bearing on the outer 5% of the fastener's wrenching points. Inclusion of dimensional data in this document is not intended to imply that all the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes. The dimensional limits of box and combination wrench lengths have been established to provide configuration control for tool storage applications. The update of AS954 is to incorporate improvements and corrections compiled from committee findings and to incorporate AS955 into the AS954 standard. Bolt clearance requirements were reorganized to promote ease of use. Corrections were made to the qualification tests for wrench design and cycle torque. The 1/4 inch drive x 9/16 inch hand universal socket and 1-5/16 through 1-5/8 inch combination wrenches were added. Torque requirements for select box wrenches were increased to ensure a logical progression by nominal size. Wrench opening depth, bolt clearance diameter, bolt clearance length, and overall length dimensions for metric socket wrenches were updated to accommodate the bi-hexagonal (also known as double-hexagon or 12-point) fasteners common in the aerospace industry.
