When people ask me how long I've been with my company, my answer usually is "since I was five".

In late 1974, my father resigned from his job as National Sales Manager of the Nylok Division of USM Corp and started R.W. Rundle Associates, Inc. Dad's first principal was  Driv-Lok, Inc., a Sycamore, IL based manufacturer of press fit fasteners.

My earliest memory of his job (aside from him bringing home a portable calculator one night and not being allowed to go anywhere near it - but that's a story for another newsletter), was when Driv-Lok would ship us their catalogs, price books and discount sheets. I couldn't wait until Dad would bring them home so I could spread out the piles on the bed and put them all together for him.
Fast forward 40 years later and while I don't have to collate catalogs anymore, we still have the privilege of representing Driv-Lok, who is celebrating their 75th year in business.

From our family to theirs - Happy Anniversary Driv-Lok!!

Our featured principal this newsletter is Driv-Lok, Inc.
Over the last 75 years, Driv-Lok has become the preeminent supplier of press fit fastener in the United States. Driv-Lok parts are found in many applications across a wide variety of industries: Industrial, Military, Aerospace, Automotive, Medical and Sports & Recreation.

Like most great American success stories though, Driv-Lok's beginnings were much humbler. In 1939, Pete Hilstrom and his wife traveled East from Iowa to visit friends from his time as an engineer at General Electric in Connecticut. A chance encounter with a old co-worker lead to Pete meeting with Ernst Von Mertens, who with one machine was trying to produce a grooved pin fastener for the Connecticut clock industry. Things weren't going as well as he hoped, and Von Mertens was selling the machine and moving on. Pete saw an opportunity, bought the machine, and moved his wife and young daughter out East. What is now known as Driv-Lok, Inc. was born in a corner of the second floor of the A.H. Nilson Machine Company (who had lent him the space) in Bridgeport Connecticut.
From man with one machine (and one customer) in 1940, Driv-Lok has grown to a company with over 90 employees (with over 1200 combined years of experience) who have shipped parts to over 40 countries around the world.

Please see the description of Driv-Lok product categories below. The company continues to grow. In 2014 they shipped over 200 million parts to over 700 customers!
Press Fit & Interference Fasteners
Grooved Pins & Studs
Grooved pins are non-threaded press fit fasteners - a fastener that is pressed into an appropriate sized hole, providing the proper interference fit to lock the fastener in place.
Knurled Pins & Studs
These are similar to grooved pins in that they have serrations around the diameter. However, knurled pins feature many more serrations.  They are press fit fasteners that, when compressed into a hole, extrude radial forces to hold the fastener in place.
Barb-Lok & Ferroll Pins & Studs
The specially designed barbs on BARB-LOK and Ferrol pins and studs provide positive fastening and replacement of conventional screws, barbed nails and other fasteners.
Slotted and Coiled
Slotted & Coiled Spring or hollow pins are economical, universally used shear-type fasteners that are self-locking. They're manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are exerted that hold the spring pin in place.
Split & Seamless Hollow Dowels 
This is an excellent cost-saving option not widely offered by other manufacturers. As a result of using less material and eliminating reaming and finishing, the Split Hollow Dowel can save you between 30-40%.
Custom & Precision Solid Dowel Pins
Solid Dowels are cylindrical pins with a centerless ground finish that provide total precision tolerances. They are used in t he same manner as Grooved Pins when highly accurate location is required.
