40mm 60mm Coach Hexagonal Wood Screws For Outside Use Construction Projects DIN571
1. Descriptions:
Our factory Crever Fastener factory offers a wide range of domestic hex lag screws for a range of fastener needs. When it comes to fasteners with forged heads, the hex head lag screw is the industry standard. We offer hex lag screws that are zinc-plated, hot dipped galvanized or 18-8 stainless steel, in a variety of lag screw sizes to meet your job’s specific construction requirements.
Our stainless-steel hex head lag screws are perfect for attaching metal to wood in situations where you are not able to use a nut. These screws are also convenient for situations where you would use a bolt but cannot find one long enough for full penetration of the wood. These screws are extremely durable, high-quality screws and can be easily used by builders of all skill levels.
Keep in mind that lag screws may be a little different than the screws you’re used to working with, especially if construction is not a part of your typical activities. These screws tend to be much bigger than ordinary screws — at least an inch long and a quarter-inch think. They also do not thread directly into the wood like typical wood screws — you will need to drill a hole first.
You will find that lag screws can support a much heavier load than a typical wood or sheet metal screw, so you’ll want to use them for more strenuous load applications. All lag screws are hex head screws, so there’s no need to specially seek out hex head lag screws.
