HTC® carbide long reach end milling cutters feature a 30 degree helix angle and are center cutting for plunging, slotting and profiling.  Designed for deep pockets in molds and cavities when ordinary end mills can't reach.  Can be ground with any diameter neck... Plus many necked tools in stock!

8 – Thread Series (8UN) is the specified thread forming method for several ASTM standards including A193 B7, A193 B8/B8M, and A320. This series is used for diameters one inch and above.

Fine Thread Series (UNF/UNRF) is commonly used in precision applications. Because of the larger tensile stress areas, they have high tension strength. However, a longer engagement is required for fine thread applications than for coarse series threads to prevent stripping.

Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter.

It's no secret that we are known as experts in the fastener industry and have been since 1912. Our devotion to customer service, quality products, and on-time deliveries have propelled us to success since our inception.

Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coarse thread is beneficial, because they are less likely to cross thread, more tolerant in adverse conditions and facilitate quick assembly.
