Threaded Rod Spec Table
This specification follows DIN (Deutsches Institut für Normung, German Industrial Standard). It is essential when maintaining German or European-sourced equipment and when supplying to the European market.
A fully threaded bolt with threads running the entire shank length, best suited for tensile-dominant loads.
Practical Notes
- Full thread takes tension along entire length — unsuitable for high shear. Use partial-thread bolts for shear loads.
- When cutting to length, always deburr cut ends. Burrs damage threads during nut installation.
Selection Guide
Full-length threading allows flexible clamping adjustment. Used as stud substitutes, ceiling pipe hangers, and leveling rods. Can be cut to length, but entire thread engagement means lower shear strength than partial-thread bolts. Use partial-thread bolts where shear loads apply.

Key Applications
Ceiling pipe hangers, threaded rod substitution, equipment leveling, anchor connections, stud fastening
FAQ
Are fully threaded bolts weak in shear?
Yes. Full threading means shear area is based on root diameter — smaller cross-section. Use partial-thread bolts for high-shear applications.
