Bolts & Screws

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.
Alcoa Fastening Systems’ 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’ 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.
