Drawing-based machine studs
Double-End Stud
Double-end studs with threaded ends and a plain center body, manufactured and sourced against the buyer-approved standard or drawing, including both thread lengths, body diameter, overall length, fit, material and finish.
- Standard number and edition or approved drawing revision
- Thread diameter, pitch/TPI, fit and hand at each end
- Overall length, body length and thread length per end
- Body diameter, thread runout, chamfer and orientation
- Material, grade, finish, quantity, packing and documents
Catalogue ranges are RFQ guidance. Final compliance is controlled by the buyer-approved standard edition, drawing, specification and purchase order.

Product overview
Both threaded ends and the body require independent definition
Double-end studs may use equal or unequal thread lengths, different fits or even different thread systems at the two ends. The unthreaded body diameter, runout and length basis also affect assembly fit.
Commercial descriptions vary by market. XHT therefore quotes only after the governing standard edition or released drawing identifies every dimension and tolerance that must not change.
What to include in your RFQ
- Standard number and edition or approved drawing revision
- Thread diameter, pitch/TPI, fit and hand at each end
- Overall length, body length and thread length per end

Technical control
Use the governing document—not a catalogue assumption
Legacy and current DIN, ISO, ANSI/ASME or customer references can define different stud proportions. Always include the exact standard number and edition or an approved drawing; a generic “double-end stud” description is not a complete manufacturing specification.
Applications & supply
Options matched to the assembly requirement
Application examples guide the RFQ. Suitability must be verified for the actual connection, service environment and governing specification.
