    Fasteners are a type of mechanical parts that are used for fastening connections and are extremely widely used. It is widely used in energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, hydraulics and other industries. It is the most widely used mechanical basic part. As a professional reliability third-party testing organization, T, C&A Lab can perform fastener tests on studs, bolts, nuts, screws, washers, rivets, etc. according to ISO, ASTM and other standards. Welcome to contact our experts for consultation.

    T, C&A Lab's test methods include but are not limited to:

    • Tensile test

    • Wedge load test

    • Hardness test

    • Surface hardness test

    • Impact test

    • Head robustness test

    • Decarburization test

    • Guaranteed load test

    • Torque test

    • Retempering test

    In addition, we also provide some other test items, such as metallurgical testing, chemical analysis, salt spray testing, nondestructive testing, dimensional inspection and failure analysis.

    Standards we test to

    ASTM F606Standard Test Methods for Determining the Mechanical Properties of Externally and Internally Threaded Fasteners, Washers, Direct Tension Indicators, and Rivets
    ASTM A193Standard Specification for Alloy-Steel and Stainless Steel Bolting for High Temperature or High Pressure Service and Other Special Purpose Applications
    ASTM A962Standard Specification for Common Requirements for Bolting Intended for Use at Any Temperature from Cryogenic to the Creep Range
    ASTM A194Standard Specification for Carbon Steel, Alloy Steel, and Stainless Steel Nuts for Bolts for High Pressure or High Temperature Service, or Both
