Type U Hammer Drive screws are designed as permanent fasteners and are not intended to be removed easily.
For most softwoods, a pilot hole is not strictly necessary, but for hardwoods, a small pilot hole is recommended to prevent splitting.
These screws feature a bronze finish, which provides good durability and aesthetic appeal.
This pack contains 1000 individual screws.
You only need a hammer or a light mallet to install these fasteners.
The bronze finish offers a degree of protection, but always check if the environment requires specific stainless steel or coated grades for long-term outdoor exposure.
Ensure the pilot hole is sufficient for the screw shank and apply a firmer strike with the hammer.
Drill a small pilot hole that is slightly smaller than the screw shank diameter to relieve tension.
For optimal results, identify if your specific material density requires a small pilot hole to prevent splitting. While these screws are designed to be self-tapping, very hard woods may necessitate a starter hole. Keep the screws in a dry environment to maintain the integrity of the bronze finish over time. When installing, use a standard claw hammer or a light mallet. Since these fasteners are designed for a permanent-style hold, consider the application carefully before installation as they are difficult to extract without potentially damaging the base material.
