8.8 10.9 12.9 Grade M6 M7 M8 Zinc Plated Hex Head Bolts And Nut
Bolts are made from a variety of materials, depending on their intended use:
Steel: The most common material, offering strength and durability. It can be further treated with coatings like zinc or galvanization to resist corrosion.
Stainless Steel: Known for its corrosion resistance, stainless steel bolts are ideal for outdoor or marine environments.
Brass: Used in applications requiring non-magnetic or decorative fasteners, brass bolts are corrosion-resistant and aesthetically pleasing.
Titanium: Lightweight and extremely strong, titanium bolts are used in aerospace and high-performance applications.
Bolts come in various sizes and thread types to suit different applications:
Metric Bolts: Measured in millimeters, these are commonly used in most countries outside the United States.
Imperial Bolts: Measured in inches, these are standard in the U.S.
Thread Types: Bolts can have coarse or fine threads, depending on the required strength and application. Coarse threads are easier to install, while fine threads provide greater clamping force.
Lag Bolts: Also known as lag screws, these are heavy-duty bolts with a pointed tip, designed for use in wood and other soft materials.
Installation and Torque Proper installation of bolts is crucial for ensuring a secure connection. Torque, or the rotational force applied during tightening, must be carefully controlled to avoid over-tightening or under-tightening. Over-tightening can strip threads or damage components, while under-tightening may result in a weak connection.
Applications
Bolts are used in virtually every industry, including: • Construction: For framing, securing beams, and anchoring structures. • Automotive: In engine assembly, chassis components, and body panels. • Aerospace: For critical connections in aircraft and spacecraft. • Electronics: In assembling devices and securing components.
