uncorrected point load strength index (Is). It must be corrected to the standard equivalent diameter (De) of 50 mm. If the core being tested is "near" 50 mm in diameter (like NX core), the correction is not necessary. The procedure for size correction can be obtained graphically or mathematically as outlined by the ISRM procedures.

Bolted Joint Design - Fastenal

strength is directly related to the net sectional area (i.e.: the amount solid bolt material in the diameter), a narrower area will result in lower bolt shear strength. To take full advantage of strength properties the shank of the bolt body should be within the shear planes. To illustrate, consider the difference in shear
