FAQ

What is the difference between the DIN 931 hexagon head bolt and the DIN 933 hexagon head screw? 

While both DIN 931 hexagon head bolts and DIN 933 hexagon head screws share similarities, the key distinction lies in their applications. Bolts are typically used with nuts to join two unthreaded components, providing a more secure connection, whereas screws are self-threading and designed to create their own internal threads within a pre-drilled hole. The choice between the two depends on your specific fastening needs.

How do I pick the correct wrench for a DIN 931 hexagon head bolt?

Selecting the right wrench for a DIN 931 hexagon head bolt involves matching the wrench size (spanner) with the bolt's across-the-flats (AF) measurement. Measure the distance across opposite flat sides of the bolt head to determine the correct wrench size. Ensure a snug fit to prevent rounding the bolt head or damaging the fastener during installation or removal.

Can I use ≈DIN 931 polyamide plastic bolts for load-bearing applications?

While ≈DIN 931 polyamide plastic bolts offer corrosion resistance and lightweight properties, they may not be suitable for heavy load-bearing applications. It's important to assess the specific load requirements of your project and consider other material options, such as steel or stainless steel, for applications where greater strength is needed. Another important thing to keep in mind is that our range of polyamide plastic bolts deviate a minimal amount from the DIN 931 standard. Hence, the polyamide bolts are ≈ DIN 931.
