How to thread a Stainless Steel Rod?
The SS 304 Threaded Rod can be threaded easily using a die. The die stock is set on one end of the rod and twisted in the desired thread direction. These rods are used in applications that require high strength and corrosion resistance. They have a good ability to join different types of fasteners.
UNJF vs UNF Threads
- UNF has finer pitch and thus, they are used in applications that require high tensile strength and clamp force. They are mostly used in industries like automotive, precision machinery, etc.
- UNJF thread comes with modified root radius for accommodating compressive stress applied during the process of thread forming. They have higher fatigue strength and can be used in fasteners undergoing high cyclic loads. They are used in aerospace industries for aircraft structures.
Difference between 304 Stainless Steel Threaded Rod (A2 or B8), 316 (A4 or B8M) and 18-8
The 304 Stainless Steel Threaded Rod has high strength and good corrosion resistance properties. The A2 Stainless Steel Threaded Rod is used in applications involving a huge amount of stress and tension.
The material is non-magnetic with high chromium, nickel and low carbon which enhance its formability. The A2-70 Threaded Rod is an acid-proof grade where cold working gives a min tensile strength of 700 MPa.
The 316 stainless steel threaded rod has better physical and mechanical properties than the 304 grade rods. Thus, they are more expensive too. The A4-70 threaded rod can be used in marine and highly corrosive environments.
The A4-80 threaded rod can be cold worked to achieve a min tensile strength of 800 MPa.
The 18-8 Stainless Steel Threaded Rod has thread along its entire length and comes with a plain finish. The material is slightly magnetic and it offers good strength and corrosion resistance.
DIN 975 vs DIN 976 Threaded Rod
DIN 975 is a standard for fully threaded rods whereas DIN 976 is for partially threaded.
What does ACME thread stand for?
The ACME thread is an American Screw thread with a section between the V threads and square threads.
