AVIATIONEU NEW ERA AN525/AN525R Structural Screws
  • AVIATIONEU NEW ERA AN525/AN525R Structural Screws


Structural screws are made of alloy steel, are properly heat treated, and can be used as structural bolts. Those commonly used in aircraft applications are manufactured to aerospace/military standards/specifications. They are offered as part of our own branded (AVIATIONEU NEW ERA) product lines structured in different series based on the standard of their conformance. Some of the screws commonly used include NAS204 through NAS235 and AN509/AN525 series. 

AN525/AN525R Series high-strength structural washer head (AN525) and cross-recessed (Phillips) head (AN525R) screws, fabricated from alloy steel per specification QQ-S-689. Tensile strength 125,000 PSI. Cadmium plated per QQ-P-416A, Type II, Class 3.  

The AN525 washer head structural screws provide a large contact area. The AN509R (100° countersunk) Phillips head screws are used in countersunk holes where a flush surface is necessary. These have been replaced by MS24694 Series structural screws of the respective materials and finishes.

Structural screws have a definite grip and the same shear strength as a bolt of the same size. Shank tolerances are similar to AN hex head bolts, and the threads are National Fine. Structural screws are available with round, brazier, or countersunk heads. The recessed head screws are driven by either a Phillips or a Reed and Prince screwdriver. Sourced from quality suppliers, AVIATIONEU NEW ERA structural screws are offered in different thread sizes and lengths in inches and sold in pieces.
