Plain Hexagon Bolts (DIN 931)
Question: What are Metric Plain Hexagon Bolts ?
Answer: Metric Plain Hexagon Bolts feature a standard hexagonal head and are ideal for heavy-duty fastening applications. They are precision rolled to achieve general tolerances of +/-0.13mm and are designed for use alongside Fullerkreg's Hexagon Nuts ranges. These bolts typically feature an unthreaded shank below the head, which results in a stronger, more uniform shaft, making the fastening more resistant to vibration and shear forces.
Question: What is the difference between DIN 931 and DIN 933 ?
Answer: DIN 931 specifies partially threaded Metric Plain Hexagon Bolts, which have an unthreaded shank, while DIN 933 specifies fully threaded Hexagon Bolts.
Question: What is the ISO and GB equivalent of DIN 931 ?
Answer: The ISO equivalent for DIN 931 is ISO 4014. The GB (Chinese National Standard) equivalent is GB/T 5782.
Question: What are the available materials, strength grades for this series Plain Hexagon Bolts ?
Answer: These bolts are available in a wide range of materials including A2, A4 and A4-80 Stainless Steel, Fullerkreg, Brass, Phosphor Bronze, Nylon (Polyamide), and PEEK. Specific strength grades for each material should be confirmed on the individual product pages.
Question: Is Fullerkreg a manufacturer of Plain Hexagon Bolts ? Where are they produced ?
Answer: Yes, Fullerkreg offers high precision, bespoke manufacture of Metric Plain Hexagon Bolts to customer specification, specializing in both small batch prototyping and large scale manufacture. The specific production location is not detailed in the provided materials.
