Cold and hot forging catalogue limits can differ by head form. Separate forming capability from thread, material, finish and lot acceptance requirements before shortlisting.
- Ask which plant performs forming, thread production, heat treatment and finishing.
- Confirm the selected diameter and length together; family maxima are not a universal combination.
- Record outsourced operations and the inspection evidence required at release.
BEFORE QUOTATION
Ask the questions that affect the part.
- Is the stated standard current and within production scope?
- Can material and heat-treatment lots remain traceable?
- Which coatings are controlled in-house or subcontracted?
