Hex Head Cap Screws are used to secure an object within or against another object. They are recognized with specific features like tighter tolerances and a chamfered end with a washer face under the head. The bare metal finish (non-plated) is ideal for indoor use or where corrosion is not a concern. Grade 8 screws, recognized by six radial bars, are made from quenched and double heat-treated medium carbon alloy steel for maximum strength in demanding applications like heavy-duty machinery.
- These bolts undergo a heat treatment process consisting of quenching (rapid cooling from a high temperature) and tempering (reheating to a lower temperature and then cooling) to achieve their high strength and toughness Double heat treated
