Fastener, also known as standard parts, is a kind of
mechanical parts used for fastening connection, which is widely used. Fastener
features: a wide variety of specifications, the performance of different
purposes, and the standardization, serialization, universal degree of high.
Selection of qualified and suitable fasteners is particularly important, the
choice of the quality of the program not only affects the life of the equipment
and related to the safety of personnel life and property.
Test range: Fastener consists of bolts, screws,
studs, nuts, screws, pins, washers, keys and gear ring, rivet, assembly and
connection, fasteners mainly involved in the routine test project: component
analysis, size, hardness, mechanical, metallurgical, coating thickness,
resistance to hydrogen embrittlement test salt spray and fracture failure
analysis, based on the standard of GB/T 3098 and ISO 898.
component analysis

Other tests:
Hydrogen embrittlement test, salt spray test,
fracture failure analysis
And according to the customer's own design program
for testing
SGS Shenzhen materials laboratory has a professional
testing equipment and a senior test engineer, can be a series of fasteners for
the standardization of testing services.
