Aerospace Fasteners

Aerospace fasteners from STANLEY Engineered Fastening range from nonstructural captive screws, stressed panel systems, and quarter-turn fastener assemblies used in aircraft, avionics, and instrument panels to high-strength bolts and stainless steel screw thread inserts designed for critical applications.

Airframe & Structural Fasteners

Airframe and structural fasteners from Heli-Coil®, and Spiralock® include wire inserts, screws, and bolts used in structural aircraft assembly or to hold fuselage access panels, landing gear components, etc.

Elevated Temperature Inserts, Bolts & Screws

Inserts, bolts, screws, and double-ended stud configurations from Heli-Coil are designed to comply with prime OEM designs, "AS" part standards, and other custom requirements.

Avionics & Panel Fasteners

Configurations include quarter-turn fasteners, captive screws, and alignment pins used in avionics, ground support equipment, and space applications. Available from POP®, Spiralock, and Heli-Coil.

Titanium Inserts & Bolts

Favored by the world's premier space/satellite companies, titanium bolts from Heli-Coil are made from several kinds of titanium alloys or A-286 CRES. Designed to meet the most stringent requirements.

Female-Threaded Fasteners
