These custom breakaway screws are manufactured domestically in the USA for our aerospace customer using 303 stainless steel material with zinc nickel plating and black topcoat. Threebond thread locking patch is applied on the flat head screw to complete the parts. The breakaway section also incorporates a hex socket recess drive to allow for faster and easier assembly. The cosmetic finish on the parts is not perfect due to the top coat getting nicked during the transport and patch application process. The high level of corrosion resistance however and mechanical properties are unaffected.
