2-1/2"crs washr hd screw. Weather-resistant 2.5" Coarse Thread self-tapping screws are specially designed for pocket hole joinery. They feature a self-tapping auger point that eliminates pre-drilling and a flat head that seats flushly in the bottom of the pocket hole. All of our screws utilize a No. 2 square drive recess. The deep recess of the square drive provides positive driver engagement to reduce cam-out. Like every Kreg product, our screws are manufactured from the highest quality materials. Weather-resistant screws are available in a weather-resistant coating which has properties similar to a zincplated screw. The coating offers protection from the elements allowing them to be used in outdoor applications. 50 count package ---- 1. 海外直輸入品となりますので、新品であっても、パッケージに多少のダメージがある場合もございますが、商品本体には問題ございませんのでご安心ください。2. 日本国内でのメーカーによる製品保証等は適用されません。3. パッケージや、説明書等は、英語表記となります。
