Wrenches, Box and Open End Combination Twelve Point, High Strength, Thin Wall, Metric

2013-02-10
CURRENT
MA4535A
This SAE Metric Aerospace Standard (MA) provides dimensional, performance, testing and other requirements for high strength, thin wall, double head box and combination wrenches which possess an internal wrenching design so configured that, when mated with hexagon (6 point) fasteners, they shall transmit torque to the fastener without bearing on the apex of the fastener’s wrenching points. This standard provides additional requirements beyond ANSI B107.9 appropriate for aerospace use. Inclusion of dimensional data in this document is not intended to imply all of the products described therein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.

Study of Wrenching Engagement on AS870C Double Hexagon (12 Point) Fasteners

2019-05-10
CURRENT
AIR1936A
This study addresses the adequacy of sockets, wrenches, and torque adapters conforming to AS954 to wrench 12 point fasteners with wrenching configurations conforming to AS870C. Reported wrenching problems with smaller sizes are investigated through examining the combined tolerances on the fasteners and wrenches, conducting torque testing on typical high strength lock nuts. Possible solutions to correct these wrenching problems are presented.

Ratcheting Wrenches, Twelve Point, High Strength, Thin Wall

2021-07-15
CURRENT
AS6405
This SAE Aerospace Standard (AS) covers high strength thin wall ratcheting box wrenches which possess the strength, clearances, and internal wrenching design so configured that, when mated with bihexagonal (12 point) fasteners conforming to the requirement 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 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.
