Dowel pins come equipped with different features depending on their intended applications. Some common dowel pin features may include:
Chamfered Ends: Chamfered ends provide easier insertion and alignment during assembly, making assembly faster and simpler.
Knurled Surfaces: Knurled surfaces provide enhanced grip and prevent slippage for a secure fit.
Grooves or Flutes: Grooves or flutes along the length of a dowel pin help distribute lubrication or adhesive, improving bond strength while decreasing friction.
Extractor Holes: Dowel pins equipped with extractor holes make removal more straightforward by requiring only special tools, easing disassembly and maintenance processes.
Oversized or Undersized Options: Dowel pins come in both oversized and undersized variations to meet any application's individual requirements for tighter or looser fits, depending on their exact purpose.
Note that not all dowel pins possess these features, and their availability will depend on both manufacturer and product line.
