Accredited Fastener Testing Lab Services

Fastener testing can include proof load, ultimate strength, tensile, fatigue, torsional, vibration, compression, and environmental exposure testing. The right test depends on the fastener material, intended application, failure concern, and governing specification. B83 Testing & Engineering can help define a test method, fixture approach, and reporting format for design validation, production verification, or failure investigation.

ISO/IEC 17025 accreditation demonstrates that a laboratory operates under recognized quality, technical competency, equipment calibration, and reporting requirements. For fastener testing, this gives manufacturers stronger confidence that results are traceable, repeatable, and generated under controlled procedures suitable for quality decisions, customer documentation, and compliance support.

Proof load testing verifies that a fastener can withstand a specified load without permanent deformation or failure. Ultimate strength testing continues loading until failure to determine maximum capacity. Together, these tests help confirm design margins, material performance, production consistency, and suitability for demanding applications such as automotive, rail, construction equipment, and power controls.

Yes. Fatigue testing evaluates how fasteners perform under repeated loading cycles that may occur during vibration, impact, equipment operation, or field use. Test setups can be developed to represent axial, bending, or application-specific loading conditions. Results help estimate fatigue life, identify weak designs, and reduce the risk of field failures.

Vibration testing exposes fasteners or fastened assemblies to random, sine, or sine-on-random vibration profiles to evaluate loosening, cracking, resonance, and durability. This is especially valuable for products used in vehicles, off-road equipment, aerospace, defense, rail, packaging, and industrial machinery where repeated dynamic stress can affect joint integrity.

Turnaround depends on test complexity, fixture needs, sample quantity, equipment availability, and whether custom methods are required. Simple mechanical tests may move faster than multi-axis fatigue, environmental, or vibration programs. B83 Testing & Engineering is known for flexible scheduling and accommodating changing client demands whenever possible.

Useful information includes fastener drawings, material specifications, heat treatment details, applicable standards, target loads or torque values, sample quantities, operating environment, and the reason for testing. If the fastener is part of an assembly, mating components and installation conditions can help the lab create a more representative test setup.

Yes. In addition to standard testing, B83 Testing & Engineering offers custom fixture design and test development capabilities. This is helpful when a fastener has a unique geometry, unusual installation condition, proprietary assembly, or field failure mode that cannot be accurately evaluated with an off-the-shelf test setup.
