Machine screws are one of the more widely used products among dozens of standard fastener types. They can be either coarse-threaded or fine-threaded, and are usually available with a wide range of head types. Usually stronger than many other screw types, they are used for fastening metal parts and panels securely together in a range of construction and other applications including aerospace, machinery, vehicles, engines, tool assemblies, electronic devices, and large-scale industrial equipment. 

Sourced from quality producers,  machine screws are offered as part of our own branded (AVIATIONEU NEW ERA) product lines conforming to aerospace/military or industrial standards/specifications.  They come in different sizes, head types, materials and thread gradings. NAS Standard Machine Screws meet aerospace standards and come in different types and sizes structured in different series including NAS1101, NAS1102, NAS1189, NAS1190, NAS1191, NAS1635, NAS1801, NAS1802, NAS220, NAS229, NAS333, NAS514, NAS517, NAS560, NAS583, NAS600, NAS623 and NAS662.
