Pre-cut dowels often have flutes for the same purpose.Īs an alternative to using wooden dowels, biscuit joints or mortise and tenon joints may be used. When cutting dowels from smooth dowel rod, a flat can be planed on one side to relieve this pressure. Requirement : Suggested Solution : Replace dowel pins with commercial locating pins. This can prevent dowel insertion or split wooden parts. Dowel pin locators do not offer desired locating flexibility. When driving dowels into blind holes, air and glue becomes trapped in the hole and significant pressure can be created. If a smooth wooden dowel is driven into a tight interference-fit hole it can form an air-tight seal, particularly if it’s coated in a layer of glue. Pre-cut dowels are also available, these normally have chamfers at each end, for the same reasons as steel dowels. These dowels may be supplied as a length of a “dowel rod” from which individual dowels of the required length can be cut. Wooden dowels are widely used within joinery, as well as traditional methods of timber frame construction and shipbuilding. Dowel pins are usually the most precise but may not be the easiest to insert and remove. Dowel pins are a type of cylindrical fastener and are ideal for service and maintenance applications as they are designed to keep components in alignment. This type of dowel is also available in other metals and engineering grade polymers.Īlternatives to steel dowel pins include roll pins (slotted or spiral), grooved pins and cotter pins. These dowels have chamfers at each end to enable insertion and to guide alignment. With dowel pins, the parts of a manufacturing machines can be safely joined and aligned together to achieve the necessary precision and accuracy. Application - These fits are for location or alignment applications between two components. Manufacturing machines require precision and accuracy. Dowel Pin - are stainless steel 304, 306, 18-8 etc. Dowel pins are used to align the parts of a machine to ensure extreme precision and accuracy. Steel dowel pins are often used in precision engineering applications for accurate location and alignment. Machines contain dowel pins for alignment purposes. A slight interference or transitional fit is typically used, which compresses the pin and generates significant friction to hold the pin securely in the holes. ![]() When a dowel pin is inserted through concentric holes in two or more components, it locates and holds them together. ![]() At its simplest, a dowel pin is just a solid cylinder of material, which is inserted through a hole. There are many types of pins used as fasteners. 090 thick wear plate welded into place which provides a positive cam stop as well as stiffens the cover to stand up to severe am loads. ![]() The reinforced cam thrust covers features a. From left to right: A steel dowel pin and a fluted wooden dowel. Each cover is precision checked for proper placement of seal and dowel pins to avoid leaks like the other off-center brands. Dowel pins are simply straight solid pins that typically have chamfered ends to aid with insertion and alignment. ![]()
