What is Zinc Plated Flat Head Screws

Zinc Plated Flat Head Screws are a popular choice for fastening applications. They are used to connect metal and wood components together.

They are available in a variety of lengths and thread sizes. They are a good option for general construction, HVAC installations and lighting.

Zinc plating is the process of coating metals with a thin layer of zinc to protect them from corrosion. This helps them last longer than they would if they were left unprotected, which saves money in the long run.

It also makes them look better by adding a clean finish. It can be applied to a wide range of different types of metals and comes with a variety of colors.

The zinc coating acts as a sacrificial anode, corroding before the base metal and acting as a protective barrier to keep rust at bay. This can help them survive for many years without the need for additional maintenance.
Advantages of Zinc Plating

Zinc plating is an effective method for reducing corrosion and rust. It is often used on metal parts such as fasteners, press handles and crank handle bolts that are subject to a high level of moisture exposure or corrosive environments.

The zinc coating acts as a sacrificial barrier and will corrode instead of the underlying metal substrate. The coating also acts as a physical barrier and can help prevent the formation of water-based oxides.

It is compatible with a variety of bath chemistries, including cyanide, alkaline non-cyanide and acid chloride salt solutions. This makes it suitable for both rack and barrel plating processes.

Zinc can be applied to a wide range of materials, and it can also be plated with a number of different types of additives, including chrome-free passivates and hexavalent chromates. It can be coated in a variety of colors, including yellow, blue and black.
Types of Zinc Plated Fasteners

Zinc Plated Flat Head Screws are commonly used in sheet metal, plastics, and other non-metal materials. They are a versatile fastening option because they have a flat bearing surface and minimize cam-out.

These screws are available in a variety of thread sizes and lengths, and are a great option for any project. They are also durable and can stand up to tough conditions, thereby increasing their longevity.

Some fasteners have a coating on them that protects the part from corrosion, and can also act as a lubricant. These coatings are applied by dipping, spraying, or electroplating.

Most fasteners are coated by the manufacturer in their factory plating plants, or they may be subcontracted out to a local coater. A chromate coating is often applied for additional corrosion resistance.

Applications for Zinc Plated Fasteners

Zinc plated Flat Head Screws are popular and economical if you're working with a pre-tapped hole and a nut. They're also a good choice when you're working with acidic woods like red/white oak in interiors.

They're also commonly used in sheet metal from.015 to.050" thick and in some plastics, impregnated plywood and other materials. The gimlet point minimizes the chance of splitting and cracking in brittle materials.

These screws are also available with a countersunk bearing surface and 4 lugs to assist with the countersinking process.

Zinc plated fasteners provide moderate corrosion protection but they will rust in harsh environments. A chromate conversion coating is necessary for use in corrosive applications or when exposed to extreme temperatures.
