Import Tips & Compliance

• Provide engineering drawings showing taper interface to distinguish from generic fasteners

• Thread pitch (e.g

• 7/16-20 UNF) variations affect interchangeability; document specific spindle compatibility

• Avoid classification as 'machine parts' by emphasizing principal function as tool retention
