Packaging Options

Nielsen Transfer Screws have several packaging options to meet our customer's needs. Since the inception of our transfer screw, we have packaged them by securing the screws in multiples of 12 to a durable card. Today, we are exploring new and innovative ways to package our products smartly so as to reduce costs and the impacts on our environment. Here are some of our packaging options:

Indexed Cards

12 count plastic card securely holds our screws in place. Plate arrangements can also be configured to hold multiple sizes and sold as sets from #0 N.C. through #4 N.C. Each card is nicely labeled with screw sizes and company branding.

Clamshell Packaging

Poly Re-sealable Bags

Loose quantities packaged in sealed poly bags. Allows for ordering in bulk and convenient for quickly grabbing and dispersing throughout your shop.





Our Nielsen Transfer Screws are the original screws that Alexander started manufacturing in 1937. The design and functionality has held true to it form since the inception because it is reliable, durable and affordable. Throw a set of these transfer screws in your toolbox today and you'll immediately see the benefits of having a precision Alexander tool.


Used by aspiring pattern makers found at local foundries, tradesmen use these transfer screws to transfer threaded hole locations to mount new parts that are going on various mold plates. Saves drilling unnecessary holes. The durable and resilient strength allows you to make countless marks in plastic, hardened aluminum, cast iron, ductile iron, tool steel, and B2 tooling steel. Since these are case hardened, you get a long lasting, durable product that delivers precision every time.

In the aviation industry, both Nielsen and Bradley-style transfer screws serve their purpose-and they do it well. Aircraft repair facilities and experimental builders get great use from these products to mark and drill the skin of aircraft and joining parts.
