Pre-drilling is recommended in hardwoods or close to the end grain of softwood to prevent splitting. Store in a dry location away from standing moisture to maintain the ZYP coating and keep the wax lubricant effective.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat does ZYP mean on screws?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eZYP stands for zinc yellow passivated.
