No. C-Serts are self-tapping.
No. C-Serts cut their way in. They make a tight interference fit. So any thread locker would just get squeezed out as the C-Sert bores in.
Friction, pure and simple. The C-Sert’s external tapping threads produce more friction than the fastener’s torque rating.
Yes, you can. Just use the same hex installer, but turn it clockwise.
Yes, you can. C-Serts are taps and can be reused, just like a tap.
If you use an impact wrench to remove a stuck bolt from a C-Sert, the L-H external threads prevent the C-Sert from backing out with the bolt.
No. Use a ratchet or, for larger sizes, a torque multiplier.
In mild steel, high carbon steel, alloy steels (like 4130), cast iron; in aluminum and magnesium; in copper, brass and bronze. They also work in 400 Series stainless, but not well in 300 Series stainless.
Yes, but only up to around 34RC.
Yes. But most applications are in blind holes.
Yes. The fastener size remains the same.
Yes. They won’t loosen, but they lose some of their hardness at over 1100 degrees Fahrenheit (base metal temperature, not ambient temperature).
From S-7 high-impact tool steel, through-hardened to 56RC. Our C-Sert Mini’s are made from 8620 gear steel, case hardened to 62RC.
An installer, cutting fluid, and instructions. And, at your option, a drill bit (for C-Serts up to 1” and 24mm). For opening up large C-Serts’ pilot holes, another option we offer is annular cutters.
