Self-drilling screws, often referred to as Tek screws, are designed to drill their own pilot holes when being driven into a substrate. This eliminates the need for pre-drilling, which saves time and labor costs. The 7% 2016 model, with its unique design and specifications, has particularly gained traction in various construction applications, from residential projects to industrial facilities.
- Time Efficiency As previously mentioned, these bolts eliminate the need for pre-drilling, significantly reducing installation time and labor costs.
Advantages of Self-Drilling Bolts
1. Select the Right Anchor Weigh your item and choose an anchor rated for that weight. Always opt for a stronger anchor if you're unsure.
The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
In the electroplating tank through the current unidirectional make zinc plating on the metal surface gradually, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance is bright, smooth, beautiful, poor corrosion resistance, generally will rust in a few months. The production process of hot wire plating mainly includes: preparation of the original plate → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection, etc. According to custom often according to plating pretreatment method.
The advantages of the blade stabbing rope (1) lightweight, high strength, never rust, good softness, fatigue resistance, impact resistance, breaking force, the overall structure is strong and durable, the service life is more than 30 years; (2) Close to nature, green environmental protection, highly effective protection of bird feathers and animal skin, effectively prevent rodents and other animals from biting, to give animals a safe and comfortable living environment; (3) Good visibility through l, luxurious appearance, novel style, itself is a big landscape. We can send you samples and make sure they are consistent. Our TECHNICIANS and ENGINEERS can also visit our factory free of charge for site investigation and design. According to your requirements and specific application environment, we can provide detailed material, rope diameter, hole distance and overall structure advice to guide installation.
Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.
The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
The type of barbed rope is mainly reflected in the specification of the wire diameter, the thicker the diameter of the barbed rope produced is shorter, at the same time, the price is cheaper, mainly because the production efficiency is relatively high, because the price of the barbed rope is calculated according to the weight when it is sold. On the contrary, the finer the diameter of the wire, the longer the price is higher.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
