Product Code:SAE J81
Title:Thread Rolling Screws
Issuing Committee:Fasteners Committee
Scope: This standard covers requirements for thread rolling screws suitable for use in general engineering applications. (It is intended that 'thread rolling' screws have performance capabilities beyond those normally expected of other standard types of tapping screws.) NOTE: The performance requirements covered in this standard apply only to the combination of laboratory conditions described in the testing procedures. If other conditions are encountered in an actual service application (such as different materials, thicknesses, hole sizes, etc.), values shown herein for drive torque, torque-to-clamp load, and proof torque may require adjustment.
