Metric Hex Head Bolts vs Hex Head Screws

How US-style “hex bolt” language maps to metric hex head screws in DIN/ISO catalogs.

Why the names differ

In many US RFQs, hex bolt means a hexagon-head fastener with a partial or full thread. Metric catalogs more often list hex head screws (DIN 933 / ISO 4017 fully threaded) or hex bolts with a shank (DIN 931 / ISO 4014).

What to put on the PO

  1. Prefer a standard callout: DIN 933 / ISO 4017 for fully threaded hex heads
  2. Thread × length (under head)
  3. Material / class (e.g. 304 A2-70 or 8.8)
  4. Nut and washer package if required

Shop hex head screws and matching hex nuts.
