Hex bolts, Hexagon head bolts, Machine bolts
Product Information
1. ISO (International Organization for Standardization)
ISO 4014: Specifies the dimensions, tolerances, and mechanical properties of hexagon head bolts with metric threads, ranging from M1.6 to M64. These bolts are typically used in general engineering applications.
ISO 4017: Similar to ISO 4014 but covers hexagon head screws with a smaller thread length.
2. DIN (Deutsches Institut für Normung - German Institute for Standardization)
DIN 931: Defines partially threaded hex bolts with metric threads, commonly used in Europe.
DIN 933: Specifies fully threaded hex bolts, often referred to as hexagon head screws.
3. ANSI/ASME (American National Standards Institute/American Society of Mechanical Engineers)
ANSI B18.2.1: Covers inch-series hex bolts, including dimensions, tolerances, and material requirements. These bolts are widely used in the United States and other countries following the imperial system.
4. BS (British Standards)
BS 3692: Specifies the requirements for ISO metric precision hex bolts, including dimensions and mechanical properties.
5. ASTM (American Society for Testing and Materials)
ASTM A307: Covers carbon steel bolts used in low-stress applications, such as general construction.
ASTM A325: Specifies high-strength structural bolts for steel construction, commonly used in structural joints.
ASTM A490: Defines even higher-strength bolts for critical structural applications.
6. JIS (Japanese Industrial Standards)
JIS B 1180: Specifies hex bolts with metric threads, widely used in Japan and other Asian markets.
Key Features of Hex Bolt Standards:
Thread Compatibility: Hex bolts are designed to match the thread pitch and diameter of corresponding nuts or tapped holes.
Material Grades: Standards specify material properties, such as tensile strength and corrosion resistance, to suit different applications.
Dimensional Tolerances: Precise dimensions ensure proper fit and performance in mechanical joints.
