I. Structural Features of Hex Socket Head Cap Screw with Flat Washer Combination
The hex socket head cap screw features a cylindrical head design with a flat top and rounded transitions on the sides, offering a sleek and simple appearance. The head contains a hexagonal socket, allowing for installation and removal using a hex key. The flat washer is a thin, circular disc with a central hole, effectively distributing the clamping pressure and protecting the surface of the connected components.
This combination is made from high-quality alloy steel or stainless steel, undergoing heat treatment and surface finishing to provide excellent mechanical properties and corrosion resistance. Its strength grades can reach 8.8, 10.9, or even 12.9, meeting the requirements of various working conditions.
II. Usage Methods of Hex Socket Head Cap Screw with Flat Washer Combination
Before installation, ensure that the hole diameter of the connecting components matches the screw diameter, and the hole walls are smooth and free of burrs. Slide the flat washer onto the screw, ensuring it sits snugly against the screw head. Insert the assembly into the connecting hole and tighten it using an appropriately sized hex key. Control the torque during tightening to avoid over-tightening or under-tightening.
For disassembly, simply rotate the screw head counterclockwise using a hex key. If rust makes disassembly difficult, apply a penetrating oil and allow it to soak in before attempting to remove the screw. Regularly check the fastening condition and promptly replace any damaged screws or washers.
III. Application Scenarios of Hex Socket Head Cap Screw with Flat Washer Combination
