Not so much because of the bolt strength, but because of the material removed for the countersink. Manufactured in the USA by Parker Fasteners, these strong externally. For something where brute strength is required (like an automotive frame), I would prefer a regular bolt, not countersunk. Socket Head Cap Screws are heavy duty screws made from DFARS sourced alloy steel. If I need either one of those, I switch to flat heads. Here's how I would choose: If centering or flush installation aren't required, I'd go with a cap screw by default. But if you need it to be flush, drilling a countersink is usually much easier than drilling a counter-bore.Ĭap screws can be installed in slots and flat heads can't (that I know of). A caps screw above the surface is the simplest mechanically. A cap head screw with an oversized hole can accommodate some misalignment without warping the parts being attached.Īlso adding to something others have mentioned. I find that this is usually an advantage, but it can also be a disadvantage. You can give the screw hole a generous clearance, and when the screw is tightened down, the parts will still be forced into alignment (in the plane perpendicular to the screw). They are self centering when used in a tapped hole. IS 2269, ISO 4762, DIN 912, BS 4168, BS 2470, ASME B18.3.Counter sunk screws have an additional advantage that I haven't seen anyone mention. 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. 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 provide you with the highest fatigue resistance if they are tightened to their respective torque figure. It allows these screws to handle the pre-load placed on it efficiently without any strain. The clamped parts get their support from stretching the screws to handle the external forces faced by it. An internal hex drive is usually used for its installation on surfaces. It is made of stainless steel, carbon steel or alloy steel making it corrosion resistant. Socket head cap screws from ITA Fasteners comply with the strictest industry standards for durability and strength.
