The shoulder bolts are also known as shoulder screws and stripper bolts. Shoulder bolts are screws with an unthreaded shoulder that is larger in diameter than the threads. The head has the largest diameter, the shoulder is described by its diameter and length, and the thread has a major diameter slightly smaller than the shoulder diameter. Shoulder bolts have a long, unthreaded, cylindrical shoulder that allows for the rotation of attached parts like pulleys, gears, moving parts of engines and mechanical assemblies, and rolling wheels. These screws are also used to attach stripper plates. They are also used as axels and pivot points.
Socket Head/Allen Bolt is a bolt with a hexagonal socket in its head that is designed to be used with an Allen wrench. The Allen bolt is integral to the crank and remains in it when the crank is removed from the spindle. The primary advantage of Allen bolts is that they are perfect if you have a bolt thatâ??s down inside a narrow opening. You can stick the Allen key down into the hole and do up the bolt. A socket cap screws are machine screws with a cylindrical barrel-shaped head containing a hexagonal socket. The head has a smaller diameter than most other machine screw heads, typically just 1.5 times the nominal thread diameter. Socket cap screws may also be referred to as a socket head cap screw, a cap head socket screw, or a hex socket head screw.
A Square Head Bolts are low or medium carbon steel, externally threaded bolt, 1/4" diameter or larger, with a trimmed square shaped external wrenching head. Square head bolts were the industry standard prior to hex bolts taking over. A square head bolt has a distinctly shaped head that makes it ideal for working in blind areas. Square head bolts are now normally used in rustic look applications. With the proper tools, tightening a square head bolt is easy even when the fastener is out of your line of vision. The head design of square head bolts enables an easier wrench grip for nut tightening. They are usually used in new construction to mimic an older aesthetic or in railway applications. Square head bolt design enables an easier wrench grip for nut tightening. They are usually used in new construction along with square plate washers and taper washers. These Bolts worked really well in the railroad industry, where supervisors could check that all bolts were on based on whether the head lined up with the tie. It is common in the railroad industry, on electrical panels, and in furniture manufacturing.

Swivel Sheetb Metal With Eye Bolt
Anti-corrosion Mechanism Duplex coating is a combination of hot-dip galvanizing and epoxy coating. Firstly, product is hot-dip galvanized, and then epoxy powder is sprayed on the surface. The anchor bolt has better anti-corrosion performance and longer service life after two kinds of anti-corrosion processes. It can not only resist ordinary chemical corrosion, but also work in acidic environment and electrochemical corrosion with stray currents. Product Standard Duplex coating combines all the performance parameters of hot-dip galvanizing and epoxy coating. Hot-dip galvanizing meets the requirements of the table below. Epoxy products are mainly based on EN 13438 Paints and varnishes - Powder organic coatings for hot dip galvanized or sherardized steel products for construction purposes, with a minimum coating thickness of 60um. Bending performance of epoxy coating complies with ISO 1519 Paints and varnishes - Bend test (cylindrical mandrel). Impact performance meets ASTM D2794 Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact). Adhesion conforms to ISO 2409 Paints and varnishes -Cross-cut test. Featurs and Advantages Excellent anti-corrosion properties: As zinc is an active metal, after coating surface is damaged, it will protect the steel by battery effect. Long service life: Zinc layer is consumed very slowly in the atmosphere, so its service life far exceeds that of any other coatings. Full protection: As immersed into hot-dip galvanizing bath�¯�¼?products are fully protected and anti-corrosion effect is better. Lower price: In most cases, the hot-dip galvanizing cost is lower. Zinc coating is more durable than others, and does not require maintenance in the future. High processing efficiency: Hot-dip galvanizing bath is simple and efficiency is higher than other coatings. After curing, the coating material will not melt even if it is heated again. It has high chemical stability. The formed coating has high adhesion to metal, low drying shrinkage and high ductility. In the case of the coating is not damaged during operation, it can effectively block corrosive substances. Service Life The service life of duplex coating anchor bolt is usually much longer than single anti-corrosion treatment, which is a synergistic effect. In most environments, the service life of duplex coating anchor bolt can reach 100 years without maintenance; the first maintenance service life of duplex coating anchor bolt in a severely corrosive environment is nearly double that of hot-dip galvanizing anchor bolt. Application Duplex coating anchor bolt is generally used in the permanent support of hydro-projects, underwater tunnels, subway tunnels and some important buildings affected by groundwater for a long time. And it is also widely used in harbors, wharfs, offshore buildings which are corroded by seawater.

High temperature oxidation resistance, resisting fire at a certain extent. 3. Stainless steel has good strength and high wear resistance. 4. Its anti-corrosion and resistance to chloride is prior to other coating re-bars due to its repairing oxide layer. Cases: Stainless steel self-drilling anchor bolt system is mainly used for tunnel and underground engineering, slope engineering, ground and foundation engineering. It can be used for pre-construction support and can effectively enhance the stability of soil and rock mass.
Anti-corrosion Mechanism Immerse the derusted anchor bar and accessories in liquid zinc for a certain time, so that the atoms can penetrate and diffuse each other, thereby forming an iron-zinc alloy layer, which is dense, uniform, firmly bonded, bright and corrosion resistant. Zinc is an amphoteric metal. In thermodynamics, zinc has a stable area. Hot-dip galvanizing is an electrochemical anti-corrosion method, which hinder further corrosion through insoluble chemical substances produced by interaction between zinc and concrete solution. Product Standard Sinorock has formulated the standard for galvanized products coatings in accordance with ISO 1461 " Hot dip galvanized coatings on fabricated iron and steel articles Specifications and test methods". The coating thickness of main products is as follows: Featurs and Advantages Excellent anti-corrosion properties: As zinc is an active metal, after coating surface is damaged, it will protect the steel by battery effect. Long service life: Zinc layer is consumed very slowly in the atmosphere, so its service life far exceeds that of any other coatings. Full protection: As immersed into hot-dip galvanizing bath, products are fully protected and anti-corrosion effect is better. Lower price: In most cases, the hot-dip galvanizing cost is lower. Zinc coating is more durable than others, and does not require maintenance in the future. High processing efficiency: Hot-dip galvanizing bath is simple and efficiency is higher than other coatings. Not affect steel performance: Hot-dip galvanizing is carried out in an environment of more than 400 �¢??, and will not affect the performance and toughness of steel. Service Life Generally, the service life of hot-dip galvanized products is more than 50 years in most environments, and it will be different according to corrosion level of the environment. According to ISO 12944-2 "Paints and varnishes- Corrosion protection of steel structures by protective paint systems-Part 2: Environmental classification" (equivalent to GB/T 30790.2), The table below lists the reference rates for different atmospheric-corrosivity environment categories.
