Introduction

Black Oxide Hex Socket Set Screws with Cup Point are used to fasten objects together, within or against another object. They have no protruding head, which means they can be flush with a top surface if required. Hex socket set screws have a hexagonal recess that is driven using a hexagonal wrench/Allen key. They are sometimes referred to as "flat head" screws. The "plain cup point" end describes the appearance of the other end, which has a concave hollow end for use in situations where digging the tip into a surface will not cause damage. These are the most common style of all hex socket set screws. They are made from 45H grade steel and have a black finish. These Black Oxide Hex Socket Set Screws with Cup Point meet DIN 916 specifications.

Feature And Application

• Used to hold objects together, within, or against another object
• Cup Point – the most common style of all hex socket set screws
• Grade 45H steel as standard
• Conforms to DIN 916 specifications

The black oxide finish provides a professional and clean look, making them suitable for use in equipment and machinery where appearance matters, such as in some consumer electronics or high-end mechanical products. The combination of the hex socket and cup point design makes Black Oxide Hex Socket Set Screws with Cup Point suitable for a wide range of applications. They can be used in various industries, including automotive, machinery, electronics, and furniture manufacturing, to fasten and secure different types of components and materials, offering flexibility in design and assembly.

Details

The black oxide coating forms a thin, protective layer on the surface of the Black Oxide Hex Socket Set Screw with Cup Point. This layer helps to resist corrosion by providing a barrier against moisture and other corrosive elements in the environment. While not as durable as some other coatings like galvanizing in extremely harsh conditions, it still offers a good level of protection in many normal industrial and mechanical applications, prolonging the screw's service life.

The cup point at the end of the Black Oxide Hex Socket Set Screw with Cup Point provides a better gripping surface and can dig into the material being fastened, creating a more secure hold. It is particularly useful for applications where the screw needs to prevent components from moving or slipping, such as in the assembly of shafts and collars, where the cup point can bite into the surface of the shaft to keep the collar in position.
