Precision Threaded Products

These critical components for aerospace fasteners are a PTP specialty. We offer knurled, threaded, stepped, and shouldered pins, as well as headed and headless slip and press fit bushings. PTP also supplies a wide variety of standard and custom ferrules to meet customer requirements. All PTP aerospace fasteners can be machined to a tolerance of ±.0002 in your choice of materials.

PTP produces Ring and Key Lock Studs in 303 Stainless, A286, 4140 Alloy Steel, Alloy 718 (INCONEL™ 718), 6A1-4V titanium and Waspaloy to MS, AN, NAS and other specifications. All studs are available in a wide range of sizes and styles in standard configurations or with standard or Lok-thread features, and with various plating options. Here are the most common part numbers we produce:

PTP produces large quantities of custom and standard MS and AS shouldered, stepped, hex wrenching, and drilled studs, maintaining pitch diameters to ±.0002. These studs are expertly produced on PTP's Swiss CNC machines; threads are rolled on advanced thread rolling equipment. Shouldered studs are produced with wrench flats up to 1 inch, lengths up to 10 inches, and in thread length configurations to meet any requirement. As with all PTP aerospace fasteners and fastener components, we can accommodate stainless, alloy or superalloy specifications.

Inserts are used in structural assemblies, such as forgings, castings and machined components where repeated bolt assembly and removal could jeopardize the integrity of tapped threads in a less durable parent material. These inserts act as a hardened thread “liner” to prevent wear and protect expensive housings, cases, or gearboxes from thread damage. Inserts are also often used to repair damaged threads in housings, and deliver performance and durability superior to original stock designs.

Specialized Bolts, Screws and Nuts – PTP is a leading aerospace fastener manufacturer, producing an extensive array of screws, bolts and nuts. We manufacture parts for Pratt & Whitney, GE, and other Tier 1 customers. These specialized parts often require custom head configurations and critical threading processes.

Thread rolling is a type of cold forging that is compatible with any ductile metal. It is the preferred method for producing strong, uniform external threads. For highest quality results, thread rolling is performed on centerless ground blanks.
