RE: nominal. 25 Aug 06 13:08. A nominal dimension is one which the tolerance is based from, which is not necessarily the optimum size. A dimension can have a Push Fit or Press Fit tolerance of say +.001/+.003 showing that the actual nominal is NOT what is required.
Nominal Consideration (Sham Consideration or Token Consideration) Applies to gifts. Nominal consideration for gifts is no consideration in contract law (e.g. $10 for $5 million dollar gift). Sham Consideration - When somebody is conveying a gift but disguising it as a sale (ie.1$ for 10 million dollars). â¢ EXCEPTION: If entering into an option contract, nominal consideration is valid.
