Socket Head Cap Screws


Description:

Socket head cap screws from ITA Fasteners comply with the strictest industry standards for durability and strength. It is made of stainless steel, carbon steel or alloy steel making it corrosion resistant. An internal hex drive is usually used for its installation on surfaces. The clamped parts get their support from stretching the screws to handle the external forces faced by it. It allows these screws to handle the pre-load placed on it efficiently without any strain. They provide you with the highest fatigue resistance if they are tightened to their respective torque figure.

Socket head cap screws are usually preferred in applications which require an aesthetically pleasing fastener for exposed views but still have enough tensile strength for better load handling. They are mainly used in applications like the construction of plastic injection molds, power plant parts and transmission tools, hydraulic braking system and home furniture.
