- Production standard of wire thread insert
Wire thread insert in China standard:
GBT 24425.1-2009 Common type wire thread insert
GJB119.1A~119.3A-2001 National military standard "ordinary type steel wire thread insert" ·GJB119.4A-2001 National military standard "ordinary type steel wire thread insert general specification" GJB5108-2002 National military standard "Steel wire thread insert installation requirements" series of standard production of steel wire thread inserts and supporting tools. Requirements for raw materials of steel wire thread insert:
Some of the requirements for mechanical properties are relatively high, especially in terms of strength, to make special Settings
Wire thread inserts international standard
According to DIN8140, MS21209, N913/N926A/N926B/N926C (GE special),
1301-SCT 149+ Uen (Ericsson special), BS 7752 (UK), MO-44421 (Toshiba Japan) and other standards
- Factors to be considered in materials
(1) Easy corrosion resistance, heat resistance
Degree, high temperature strength, oxidation resistance requirements, to focus on the design;
(2)According to the production process of material processing performance production, in the material product weight, price, procurement and many other factors should be considered in detail;
(3)According to the working environment and working conditions to choose, the basic equipment can be configured with ordinary thread insert fastener materials; Locking fasteners and other high strength and tightness requirements to use relatively high performance materials;
(4)Hole depth requirements, body antibody strength, thread performance grade requirements to determine the material of the thread insert, while distinguishing the characteristics of the thread insert fastener products, such as stainless steel, aerospace specifications, non-standard specifications, etc.
(5) The starting point of material selection of fasteners includes the production process method of fasteners, the size and shape of fasteners, and the production number of products or series of products with the same specifications
After comprehensive consideration of many aspects, the selection of steel wire thread insert is determined, and then the standard brand, variety, specifications, material standards, etc., in-depth and detailed consideration and design is the inevitable way to create high-quality, high-performance fastener products.
