Socket set screws, also known as grub screws, are designed to secure a pulley or gear to a shaft and prevent any unwanted movement in the power transmission systems. They help create compression forces which hold two loose objects firmly without relying on a nut. Raptor Supplies offers a wide range of set screws from brands like Fabory, Camcar, Grainger, Raco and Unbrako, Micro Plastics, RWM and Nord-Lock.
Withstands wear & tear; resists abrasion, moisture & chemicals and provides non-marring properties.
Provides superior strength, improved toughness and corrosion-&-wear resistance.
Corrosion, heat and fire-resistant properties with moderate structural rigidity.
Offers durability and resists rusting & other types of corrosion.
Provides hardness, structural rigidity and durability.
Low-&-medium rated carbon steel offering excellent machinability, weldability and formability for easy rolling / bending.
Stainless steel with excellent corrosion resistance, moderate structural rigidity and aesthetic appeal.
304-stainless steel having 18 per cent chromium & 8 per cent nickel, offers corrosion resistance and the ability to withstand high stresses.
A type of stainless steel with 16-30 per cent chromium and a varying amount of nickel and / or manganese for resistance against high temperature & corrosion.
Low resistance to corrosion and improved appearance.
Mild to high corrosion resistance in wet & humid environments.
Light-to-medium corrosion resistance and minimises light reflection.
Chemically coated to remove free iron and other surface contaminants from stainless steel, providing high resistance to corrosion & rust.
Screw sizes, in this system, use the diameter of the shank and the length / pitch of the screw in millimetres.
Screw sizes are measured using the diameter of the shank and the length of the screw. The diameter is measured in fractions of an inch while the length is measured in inches.
It has a convex oval point on one end that allows repeated adjustments without damaging the mating material or part. It is ideal for U-or V-shaped grooves and sloped / angled surfaces.
It includes serrations on the cup edge to provide strong holding power in high-vibration applications.
It features a threaded body with a small, cylindrical protrusion to provide a non-slip connection and enable free rotation.
It has a cup-shaped indentation at one end and a socket / slotted head type at the other. It creates a deep & secure grip when tightened and resists loosening due to vibration.
It features a smooth surface with a sharp point to fasten two objects with greater compression force and pressure. This point type is ideal for high-vibration applications.
It features a tubular tip with half the length of a dog point set screws to mate with the corresponding hole in the workpiece & allowing the shaft to rotate freely without dislodging the part.
It has a hexagonal recess and a threaded body to make good contact on flat surfaces while distributing the load evenly.
Knurled cup point screws are typically used on softer materials, such as plastics, wood and soft metals.
Choosing the right size socket screw depends on several factors, including the size of the object being fastened, the amount of pressure required and the material of both the screw and the object being fastened.
Some set screws are not designed to be adjusted once seated. Knurled screws, for example, provide a more permanent fixture. However, in certain situations, like the loosening of screws or incorrect positioning, the screws can be reinstalled using a Wrench for a clean look.
