PTP - Quality


Aerospace Bolt Quality

PTP strives for continuous improvement by prioritizing 100% customer satisfaction, and delivering product on schedule, to locations worldwide.

We maintain AS9100D and ISO 9001:2015, and hold a Laboratory Control at Source (LCS) designation for Pratt & Whitney.

PTP is an accredited supplier of high strength fasteners by Collins Aerospace (formerly UTC Aerospace Systems-UTAS) and PWA-LCS certification and GE Direct Source, and is included on DLA’s QSLM for Class 3 Threaded Fasteners. PTP has a robust internal Quality Management System (QMS) and is Federal Government / Military Build-to-Print approved.

Incoming material verification is performed for compliance to chemistry, certification and end use applications.

Complete specification testing is performed per customer requirements. Dimensional inspections are performed per sampling guidelines in accordance with ANSI 21 .4, ASQR20.1, S-1000, C=0. PTP covers a wide variety of material microstructures and is versed in many aspects of materials science.

Mechanical Testing

    ISO 9100:2015 and AS9001:2016 certification, and Approved Laboratory Controlled Source (LCS) for Pratt & Whitney.

    The PTP tensile tester is P&W approved.

  • PTP Quality Technicians perform microscopic and macroscopic thread inspection on all rolled product as part of the thread rolling process. Tests quantify grain size and grain flow, and identify laps and discontinuities. Tolerances are held to ±.0001".
  • PTP technicians tensile test using a Tinius Olsen system, which precisely indicates proof loads and ultimate tensile strength. Accuracy is ±.0.1 % of the indicated load, from 0.2% to 100% of frame capacity.
  • PTP’s quality department also operates a Keyence Image Dimension Measurement system to precisely determine part ODs and lengths and other exterior characteristics. Exceptionally fast and accurate, it accommodates multiple parts simultaneously.
  • Sunnen bore gauge testing measures to .00005".

PTP also offers:

  • Compositional analysis
  • Thread analysis
  • Semi-quan analysis
  • Torque and pull-out analysis
  • Full chemical analysis per AMS spec
  • Stress rupture testing as an adjunct to standard tensile testing
  • FPI/MPI (Fluorescent Penetrant and Magnetic Particle Inspection)

Advanced 2D barcoding is used for inventory control, with over 2000 SKUs maintained.

Documentation, including certifications and test data, is maintained for ten years minimum, or per customer requirements. Records are available upon customer request.

PTP is now certified to manufacture HS4773 studs for Boeing and its suppliers.
