Bolts & Screws

The bolts and screws manufactured by Alcoa Fastening Systems & Rings meet and exceed the most exacting requirements of the aerospace industry. Alcoa Fastening Systems & Rings’ 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.
Alcoa Fastening Systems & Rings’ technical, metallurgical, and manufacturing skills are applied to produce high-strength bolts. This talent serves to match the kind of structural materials and finishes used on present-day airframes and engines with fasteners of absolute reliability and superior strength. Depending on choice, considerable weight savings, superior corrosion resistance, and high strength-to-weight ratios may be gained. Configurations include hex,12-point, D-head and spline head. Custom designs are also available to meet our customers’ exacting requirements.
The selection of recess drives available on Alcoa Fastening Systems & Rings’ externally threaded products is comprehensive. The popular Cruciform-Ribbed drive with its cam-out resistant features is just the beginning. The Offset-Cruciform recess fastener system provides torque-tight, tamperproof screws or bolts. The slanted three-wing design of the Tri-Slot screw recess ensures reliable insertion at above average torque, and for optimum security, only the mating Tri-Slot driver can remove the fastener. The Torx® and Torx Plus® recesses provide tightreduced risk of both recess damage during installation, and damage to the structure when fasteners are removed.
