Nylon 6/6— The most common plastic nuts, these are good for general purpose fastening. They are slippery and abrasion resistant, so they thread on smoothly and stand up to daily wear and tear. Nylon will swell and weaken when exposed to moisture, so these nuts are best for dry environments.

High-Strength Glass-Filled Nylon—Glass fibers embedded in the nylon give these nuts better strength than nylon 6/6. They can also handle higher temperatures without losing strength.

Thin-Profile Hex Nuts

About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
