About this tool
This is a tool in Carbon Steel, supplied red, with an 1/4-20 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A fitting, driving or measuring tool matched to the fastener sizes we stock, so the drive and the head are known to fit before you buy. Used for installation and inspection work, and for checking thread and dimension before an order goes into production.
A non-metric or special bore size. Confirm the thread form and tolerance with us before you specify it into a design.
Carbon steel is the workhorse material for structural fastening. Grade 8.8 and above must be coated (zinc, black oxide or Dacromet) or it will rust outdoors.
This line ships worldwide from our own warehouse. Express courier, air parcel and postal services are all offered at checkout, with a tracking number e-mailed as soon as the parcel is handed over.
