Hex Head Screw

The majority of machinery and equipment can be fastened with these Class 8.8 steel screws. 

For high-stress applications like motors, pumps, valves, and suspension systems for automobiles, use these Class 10.9 steel screws. Compared to medium-strength steel screws, they are at least 25% stronger. 

Select these Class 12.9 steel screws for use with earth-moving equipment like excavators and bulldozers, as well as for heavy-duty stamping applications. They are 10% more robust than our other metric steel screws, with a tensile strength of 170,000 psi. 

These stainless screws are very resistant to sea water and chemicals. 

These 17-4 PH stainless steel screws are appropriate for high-strength fastening in hostile settings because they combine the strength of steel with the corrosion resistance of SS304 stainless steel. Screws have a magnetic property. 

Plastic screws are chemically and oil-resistant, nonconductive, and light. Not approved for use in high-strength fasteners.

When nylon screws come into contact with moisture, they may expand. PVC screws are more resistant to oil, grease, and alkalies than nylon screws. Unlike nylon screws, they do not absorb moisture. PTFE is our most corrosion-resistant plastic screw. They endure salt water and acids, do not absorb moisture, and outperform other plastic screws in harsh temperatures. 

In addition to being nonmagnetic and electrically conductive, brass screws also resist corrosion well. 

The weight of aluminum screws is one-third that of steel, and they are resistant to corrosion. 

Titanium screws are the most corrosion-resistant metal screws we provide; they can tolerate chemicals, sea water, and acids. They are roughly 40% lighter than medium-strength steel screws and have a great strength-to-weight ratio. 

In addition to being 30% stronger than brass screws, bronze screws are more resistant to corrosion from sewage, gasses, and salt water. They carry electricity and are nonmagnetic. 

These nickel alloy screws exhibit exceptional resistance to salt water and certain acids, making them more corrosion-resistant than 316 stainless steel. Monel screws are another name for them. The material satisfies the quality requirements of MIL-S-1222 and ASTM F468. 

These glass fiber-reinforced polyurethane screws are lightweight, nonconductive, and stronger than our plastic hex head screws. They are more resistant to acids, solvents, and oil than PVC and nylon screws. They are not prone to absorbing moisture like nylon screws are. 

Even at very high temperatures, ceramic screws won't melt, corrode, seize, or break. They have a great resistance to corrosive gasses and are nonconductive. 

These steel screws, which are the most widely used heavy hex head screws, adhere to ASTM A325 standards for structural joints, including scaffolding and mating I-beams. 

These steel screws, which are 50% stronger than our medium-strength steel heavy hex head screws, are suitable for structural applications including scaffolding and mating I-beams and comply with ASTM A490 standards. When joints need greater tensile strength than ASTM A325 screws, use them. structural bolts, as well. Only the stronger unthreaded component (grip) of screws can be used in joints that are subjected to sideways forces because they are partially threaded and have precisely threaded and unthreaded portions. 

These metric screws, which are made for outdoor building and construction applications, are frequently used to connect scaffolding and I-beams. An unthreaded section that is robust enough to withstand the sideways forces of joints is left over after their partial threading. Additionally, they won't rust in damp conditions because of their hot-dipped galvanized coating, which is ten times more corrosion resistant than zinc plating. 

These Grade B8M screws are made of stainless steel and have superior resistance to chemicals and sea water, making them more corrosion resistant screws. They might have a slight magnetic field. These screws, often referred to as pressure bolts, are used to fasten pressure tanks, valves, and flanges and satisfy ASTM A193's high-pressure and high-temperature requirements. 

For high-pressure applications, these Grade B7 steel screws are almost twice as robust as our stainless steel screws. Often referred to as pressure bolts, they are used to fasten pressure tanks, valves, and flanges and satisfy ASTM A193's high-pressure and high-temperature requirements. 

For high-stress applications like motors, pumps, valves, and suspension systems for automobiles, use these Class 10.9 steel screws. There is no need for an additional washer because the flange distributes pressure where the screw touches the surface. 

The majority of machinery and equipment can be fastened with these Class 8.8 steel screws. There is no need for an additional washer because the flange distributes pressure where the screw touches the surface. 

These screws, which are made of 304 stainless steel, may be slightly magnetic and have strong chemical resistance. There is no need for an additional washer because the flange distributes pressure where the screw touches the surface. 

Use a screwdriver or wrench to install these screws. There is no need for an additional washer because the flange distributes pressure where the screw touches the surface. 

These screws are lightweight, nonconductive, and resistant to chemicals and oils since they are made of polyurethane reinforced with glass fiber. There is no need for an additional washer because the flange distributes pressure where the screw touches the surface. 

The flange disperses pressure where the screw contacts the surface, removing the need for an additional washer, and serrations beneath the head grasp the material surface providing mild vibration resistance. 

To prevent a nut from loosening, insert a cotter pin into the shank's hole. Compared to screws with thread lockers or lock washers, these screws have a stronger grip. Screws are incompatible with coarse or extra-fine threads because their fine threads are closely spaced to avoid loosening from vibration. 

For greater vibration resistance than any other screw, connect these screws via the head's hole. 

These screws, often referred to as Sems screws, feature a teeth lock washer that is freely moving but permanently connected, biting into the mating surface to provide vibration resistance. 

Under the head, an O-ring seals out impurities and stops leaks. The O-ring, which is made of silicone, can tolerate temperatures up to 400° F, sea water, and most acids. These 304 stainless steel screws may be slightly magnetic and have strong chemical resistance. 

Unlike a flange, a freely spinning but permanently connected washer disperses pressure across a larger surface area, protecting the surface of your material. Sems screws are another name. 

These screws are suitable for vacuum applications because they vent fluid and gases trapped beneath them through holes drilled through the head and shaft. 

When the screw is tightened all the way, an indication dot turns from red to black. The dot becomes red again if it falls loose. Another name for them is SmartBolts. These Grade 8 steel screws are suitable for high-stress applications like motors, pumps, valves, and suspension systems in automobiles.
