We get many questions about countersinks and proper dimensioning of countersinks. So we thought we would give you the Top 4 Standard Countersinks that the metal fabrication industry commonly uses. This should be very helpful for many of the engineers out there that are looking for functionality without the cost of special tooling.

  1. 82˚ Countersink:   1.74 x T = XX – C = M
  2. 90˚ Countersink:   1.74 x T = XX – C = M
  3. 100˚ Countersink: 1.74 x T = XX – C = M
  4. 120˚ Countersink: 1.74 x T = XX – C = M
