Knurled Pins, Knurled Studs

Knurled PinHartford Technologies custom-manufactures precision knurled pins and knurled
studs that provide the highest levels of straightness, roundness, and hardness,
without marks. Hartford knurled pins and knurled studs are manufactured in high volumes in straight, diamond and helical styles, tapered and untapered. A wide range
of lengths, diameters and pitch is available; material options include chrome steel, low carbon steeland stainless steel.   

Knurled sections can have a straight, helical, or diamond knurl configuration, and a variety of custom end configurations. Knurled pins are available with diameters up to3/8" and lengths up to 3".

Knurled pins are ideal for assembling parts with thin sections, and, because of their greater number of serrations, are superior to grooved pins in fastening capacity, particularly where the application is subject to vibration and other mechanical shock.
