About PIC Design®

PIC Design - Middlebury, CTPIC Design was founded in 1954, operating as Precision Industrial Components, LLC. PIC Design was the first company to satisfy the need for pre-engineered gear products in the United States and was one of the original mechanical component "catalog" companies, inspiring many imitators. As the pioneer and leader in the field of precision gears and mechanical components, PIC has always maintained a very high standard of quality and service. PIC continues to stand above the competition by expanding beyond its diverse range of gear products, offering a one-stop shop for precision, high quality mechanical components.

PIC Design is located in the Naugatuck Valley of Connecticut, an area known for its diverse manufacturing base. Our facility is equipped to manufacture your custom designs or high-volume orders. PIC Design's experienced staff supports our reputation for quality, evident by our loyal family of customers.

In 2008, PIC Design joined RBC Bearings, a leader in the world of highly engineered bearing products. PIC Design’s manufacturing and applications engineering experience, combined with RBC Bearings’ global technical resources, provide our customers unsurpassed capabilities to satisfy their application demands.

Dowel Pins, PIC Design

PIC Design specializes in high-quality, precision stainless steel dowel pins. Dowel pins are a fastening device used for alignment or to hold parts together in an assembly or fixture. They can also be used as locators so that a part can be removed and will retain its accurate location when replaced.

The following specifications define our standard dowel pins sizes, fit specifications and materials options: 

  • Diameter: 1/32’’ to 1/2’’, 1 mm to 12 mm
  • Length: 3/32’’ to 1 ½’’, 3 mm to 50 mm
  • Fits - Slip, Press/Interference
    • Slip Fit: The dowel pin has a smaller diameter so that it freely slips into the hole
    • Press Fit: The dowel pin has a larger diameter and must be pressed into the hole
    • Tolerance: Slip (+.0000/-.0002) and Press Fit (+.0002/-.0000)
  • Standard Material: 303 Stainless Steel, 416 Stainless Steel - Hardened to 36-42Rc, Carbon Steel - Hardened to 60Rc

Shoulder Screws, PIC Design

Shoulder screws are typically used as fasteners to join two pieces of an assembly where maintaining alignment is critical.  The requirements and constraints of a project sometimes call for a standard shoulder screw, however, PIC Design also offers custom shoulder screws when necessary.

Standard screws are available in the following dimensional ranges:

  • Shoulder Diameter: 1/8’’ to 1/2’’, 4 mm to 12 mm
  • Shoulder Length: 1/8’’ to 1’’, 4 mm to 25 mm
  • Head Style: Socket, Phillips, or Slotted
  • Standard Material Options: 303 and 416 Stainless Steel

Couplings, PIC Design

PIC Design carries a full range of flexible coupling options, manufactured and supplied with or without corresponding shafting. Specialized in high-misalignment, PIC Design’s coupling products feature a wide range of styles and types to suit almost any application.

Each coupling is available with clamp, pin, or screw attachment configurations. PIC Design Coupling types are as follows:
