Screw Wax, Is the approved lubricant to ZIPBOLT products. The perfect companion for installation of the ZIPBOLT products. Professional cabinet and furniture makers have used wood screw lubricants for over one hundred years. The simple but effective technique saves them time and money. Wood screws and fasteners are easier to drive, screw heads are harder to strip or break and the wood is less likely to split. Screw Wax's unique beeswax-based formula is soft, sticky and non-flaking. It outperforms the competition... including plain beeswax. It is non-petroleum based and made from 100% natural waxes so it is environmentally and ecologically safe. None of its ingredients are on the California Prop 65 list. Screw Wax is Made in the USA.
