Top 12 Set Screws

The minimization of non-essential components in any form of machinery is a core aspect of engineering and carpentry work. Removing redundant non-functional parts from any fixture or engineering contraption leads to construction efficiency and significantly reduces the odds of machinery breakdowns. Moreover, the lesser the number of parts, the easier it will be to repair machines and mend broken furniture. One key component common in engineering and carpentry work is the fastening of various parts, which is traditionally accomplished by the classic nuts and bolts. However, the benefits offered by set screws are more substantial.

 Why set screws, and why not nuts and bolts?

Optimization is the core philosophy of engineering. Any form of innovation and breakthrough in this field has always been a variation of the “one is better than two” philosophy. When a piece of work is accomplished by one component instead of two, then the single component responsible for the work is recruited.  The fastening of components, which is traditionally achieved through nuts and bolts forming two whole components, is also achieved by a set screw, an entire single component. It is because of this redundancy removal that set screws are preferred over nuts and bolts.

What are the set screw tips?

In a two-part mechanism that requires fastening, the set screws are inserted into the threaded hole, enabling the screw to secure its grip on both the components. Hence, the critical factor for ensuring a stable and sturdy grip is the set screw. Set screw come in multiple varieties, all of which cannot be described. However, a few important ones like the cup point and the knurled cup are worth mentioning since the two are predominant screw tip types.

The cup-point and knurl-cup dichotomy

Where set screw tips are concerned, engineers and manufacturing companies are polarized on the correct tip type. While many swear by the cup point tips, many others emphasize the knurl cups. Cup point tips are the most common type of set screw that is excellent at holding parts permanently and is versatile regarding the kind of surfaces they are capable of holding. However, knurl cups are more heavy-duty in their applications because they have the added capacity to resist vibratory force, making them useful in production lines and conveyor belts.

Set screws and their drive types

Based on how they are driven into the components, set screws are divided into three types: the straight slot, the hex socket, and the square socket. Straight slots are most common in woodwork and DIY applications and are driven in by flat-bladed screwdrivers. Hex sockets are meant for hexagonal recesses and are driven by an Allen Wrench, whereas square sockets are used for square-shaped protrusions that are also driven by a square-tipped Allen Wrench.
