Drywall Screw
Material: C1022 steel; finished screws to be further heated/hardened.
Finish: Black/grey phosphate, yellow zinc-plated, blue zinc-plated, and others.
Head Type: Bugle head/Countersunk head
Thread Type: Coarse or Fine

Features:
1. Made of case-hardened steel, the screws offer strong pull strength to hold the drywall.
2. Sharp points for easy to screw in and minimal damage.
3. Black phosphate coating to increase durability.
4. Commonly used with a corrosion-resistant coating.
5. The salt spray test ensures that no color stains the wall.
6. Speeds up the drywall installation process.
7. Long service life.

Drywall Screw Terminology and Features:
1. Bugle head: Bugle head refers to the cone-like shape of the screw head. This shape helps the screw stay in place without tearing all the way through the outer paper layer.
2. Sharp point: Some drywall screws specify that they have a sharp point. The point makes it easier to stab the screw into the drywall paper and get the screw started.
3. Drill-driver: For most drywall screws, you will generally use a #2 Phillips head drill-driver bit. While many construction screws have begun to adopt Torx, square, or heads other than Phillips, most drywall screws still use Phillips heads.
4. Coatings: Black drywall screws have a phosphate coating to resist corrosion. A different type of drywall screw has a thin vinyl coating that makes it even more corrosion-resistant. Additionally, they are easier to drive in because the shanks are slippery.

Installation Steps for drywall screws:
1. Drywall screws are easy to use if you choose the right screws and properly driven fasteners.
2. Select the appropriate size of drywall screws. Ensure that the length of the screw is at least 10mm more than the thickness of the drywall.
3. Mark off where the studs are, and lift the drywall panel to the right place. Make sure the screws are no less than 6.5 mm from the edge of the drywall.
4. Adjust the screw gun to the proper depth, and put the collated drywall screws on it.
5. Hold the drywall tightly, and use the screw gun to drive the screws into the drywall and base materials.
6. Remove the screws that missed the studs.

Product name: Zinc-plated twisted roofing nails
Material: Q195
Finish: Electro-galvanized, hot-dipped galvanized.
Head: Round flat head or umbrella head.
Shank type: twisted
Point: diamond
Surface treatment: galvanized, hot-dipped galvanized.
Package: As per client requirement.

Features:
1. Galvanized to reduce rusting.
2. Large head with a diamond point.
3. Designed to fix the roofing

Roofing nails are perfect for construction work with soft sheet material. They are designed to fix the roofing materials to the wooden base. Roofing nails have a corrugated surface of the socket head cap characterized by increased diameter.

Roofing nails are made of conventional heat-treated steel wire or low-carbon steel. As a rule, they are zinc-coated to ensure corrosion resistance. And uncoated nails also available.

Galvanized roofing nails are used to fix the roofing felts, thin sheet metal, and other sheet materials for wooden structures. The large head creates a large area of attachment. Galvanizing protects nails from premature corrosion.
