Bolts, Recess Fasteners, Externally threaded NAS, MS and AN Standards and BAC Standards.
The bolts and screws manufactured by Alcoa Fastening Systems meet and exceed the most exacting requirements of the aerospace industry. Alcoa Fastening Systems’ designers and manufacturing engineers provide the accumulated knowledge and experience necessary to develop bolts in materials such as alloy steel, corrosion resistant steel, Inconel® 718, Waspaloy®, titanium, and other super alloys. From micro-screws (1.6mm in diameter) to bolts up to 1-1/4 inch in diameter, and in lengths up to 14 inches, this vast product range is available in both unified and metric sizes.
Our recess fasteners meet and exceed the most exacting requirements of the aerospace industry. The selection of recess drives available is comprehensive. The popular Phillips® ACR drive with its cam-out resistant features is just the beginning. The Torq-Set® recess fastener system provides torque-tight, tamperproof screws or bolts. The slanted three-wing design of the Tri-Wing® screw recess insures reliable insertion at above average torque, and for optimum security, only the mating Tri-Wing driver can remove the fastener. The Torx® recess provides reduced risk of both recess damage during installation and damage to the structure when fasteners are removed. The conical Connie Hi-Torque recess assures positive alignment of tool and recess at the beginning of installation, and is ideally suited to handle the stresses of hostile environments.
