SAE J429 grade 8 bolts do not exceed 1-1/2" diameter.

1 - Proofload is the published number that full size headed bolts are tested to. The bolt is stressed up to the proofload value, and if there is no deformation, elongation, or fracture, then the bolt is deemed to have passed. For bolting specifications that do not have a published proofload, it is usually calculated at 92% of ultimate yield strength.
2 - Clampload is calculated at 75% of proofload. This is done to allow a safety buffer so that the bolt does not get too close to the proofload value. If you exceed the proofload value when tensioning the bolt, you run the risk of bolt failure. Clampload is only a estimated number, there maybe situations where the engineer calls for the bolts to be tensioned to a different value.
    Notes:

  1. Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb.
  2. K values: waxed (e.g. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts (as received) = .20.
  3. Torque has been converted into ft/lbs by dividing the result of the formula by 12
  4. All calculations are for Coarse Thread Series (UNC).
  5. Grade 2 calculations only cover fasteners 14"-34" in diameter up to 6" long; for longer fasteners the torque is reduced significantly.
  6. Clamp loads are based on 75% of the minimum proof loads for each grade and size.
  7. Proof load, stress area, yield strength and other data is based on IFI 7th Edition (2003) Technical Data N-68, SAE J429, ASTM A307, A325, A354, A449, and A490
