Test Bolt (with dime)

While applying lubricant to the threads of a bolt has little effect, lubricating the washers results in a noticeable decrease in friction.

Lubricants are important for decreasing friction and wear, thus improving bolt life.

Lubrication also improves consistency and can help the fastener adapt to different environments.
