Generic Carbon Steel Hex Head Allen Grub Screw Size M6x8 mm, FAGSM68 (Pack of 100 Pcs) is a type of threaded fastener with a unique drive system and no head. Unlike typical screws with heads, the Allen grub screw features a threaded shaft along its entire length, making it ideal for specific applications where a flush or recessed installation is required.
The key characteristic of an Allen grub screw is the presence of a hexagonal socket or recess at one end, which accommodates an Allen wrench or hex key. This socket allows for precise tightening or loosening of the screw by inserting the tool into the recess.
Allen grub screws are available in various materials such as stainless steel, alloy steel, and brass, to suit different environmental conditions and applications. They come in various thread sizes, lengths, and tip configurations, including cup point, cone point, flat point, and dog point, depending on the specific use case.
One of the primary purposes of Allen grub screws is to secure components or objects in place by being tightened against another part. They are commonly used in machinery, devices, and equipment to prevent the relative motion of parts, alignment adjustments, or locking mechanisms. For example, they are frequently employed in securing pulleys on shafts, locking gears, or adjusting the position of sliding components.
The absence of a head in Allen grub screws allows for a flush, inconspicuous appearance when installed, making them suitable for applications where aesthetics are important. They are also used in assemblies where space is limited or where a traditional screw head might obstruct other components.
In summary, Allen grub screws are specialized fasteners with a threaded shaft and a hexagonal recess at one end for precise installation and adjustment. They are used in applications where a flush, unobtrusive fastening solution is required, often playing a crucial role in securing and aligning various components in machinery, electronics, and other devices.
