Quality

At LoneStar Fasteners, we are proud of our Quality Program and the reputation that it has brought us. The foundations of our outstanding quality program are the procedures that have been certified to the following criteria:

ISO 9001:2008      BS 5750      MIL 45208

We welcome all audits by our customers and treat them as an opportunity to validate our value in the relationship with our clients.

Our commitment to quality products is reflected in the in-house testing laboratory used to mechanically test fasteners for tensile and proof strength, and includes:

• State of the art metallurgical examination using Leica microscope and Struers software.
• Heat Treating and Material testing capabilities
• Full Mechanical Testing (Tensile/Proof to 300,000 lbs.)
• Spectrometer testing and full elemental chemistry.
• Charpy Impact testing to -320º F
• Salt Spray Testing Per ASTM B -117
• Hardness testing (Rockwell, Brinell, Eddy Current)
• 3 Digit heat Code Traceability
• Access to all Material Test Reports (MTR) on our Web Site

Procedures for Conformance Testing of Materials have been developed to insure:

• The mechanical and chemical integrity of raw materials and finished goods.
• Adherence to ASTM Specification requirements
• To identify the quality of our vendors.

Traceability - all studs are stamped with a three digit code for heat code traceability. This heat code is accessible by Lone Star customers through our Web Site, by using a unique password, and MTR’s can be printed any where in the world.

SPC Gauging System at the point of manufacture. Dimensional tolerances are set in a narrow range to assure accuracy. Direct recording of gauge readings to our computer enables us to analyze trends in die wear and eliminate non-conformances.
