Machine Screws
stainless steel | carbon steel | alloy steel | specials
Phillips pan head machine screws from ITA Fasteners are made with stainless steel. This makes the screws resistant to corrosion and rust. These screws mostly find their application in metal to metal or high-density timber-to-metal fastening. They are commonly used in the automobile industry as well as in machinery equipment installation. It requires a pilot hole to be drilled before using the machine screws.
The slotted or Phillips head comes with a straight slot on the head and can be drilled or removed using a screwdriver. However, for ease of operation, we recommend using a Phillips head screwdriver. This ensures minimum damage to the surface of operation. We have stock of these screws in several sizes depending on the requirement. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant. Our screws comply with the most stringent quality standards in India for fasteners. We also undertake custom orders for different sizes and materials.
