what is the Classification of hexagon socket bolts ?
With a hexagonal socket on its head, hexagon socket bolts-also known as Allen bolts,they are a kind of fastener that may be tightened or loosened with an Allen wrench or hex key.
Classification by thread length:
Fully threaded hexagon socket bolts: The threads cover the entire shaft, suitable for occasions requiring greater tensile strength, such as steel structures, mechanical equipment, etc.
Half-threaded hexagon socket bolts: The thread length accounts for a portion of the shaft, suitable for connecting thinner materials, such as wood, plastic, etc.
Threaded rod hexagon socket bolts: There is no thread on the shaft, usually used with nuts to adjust the length.
Classification by use and structure:
Hex socket bolt tightening: For situations where anti-loosening is necessary, built-in spring washers offer extra tightening force.
Double-head hexagon socket bolts are appropriate for items that are regularly disassembled since they have hexagonal heads on both ends.
Classification by material:
Stainless steel hexagon socket bolts: Available in SUS202, SUS304, SUS316 and other materials, with good corrosion resistance.
Iron hexagon socket bolts: Available in strength grades of 4.8, 8.8, 10.9, 12.9 and other grades, suitable for different strengths.
