Zip Screws and Tek Screws!

Self tapping screws, such as zip screws and tek screws, are ideal for jobs when you plan to attach material that are of different kinds, such as wood to metal, metal to plastics and metal to metal. Self tapping screws are extremely versatile and simple to use since they will tap their own threads as you drive them into your material, and this in turn will save you time and time equals money! There are many kinds of self tapping screws you can buy today and they each have their own purpose. 

There are basically two types of popular self tapping screws available, zip screws and tek screws. Type A screws are also self tapping, as they tap their own threads, however, they are not as popular as they normally need a pilot hole to get them started. There are two types of tips for self tapping screws and that they are the self piercing screw, also known as zip screws, and the other is the drill bit tip, tek screws tek screw type. Self tapping screws can sometimes need a pilot hole which is much smaller than the diameter of your self tapping screw, this way your screw can have enough material to create its thread and attached itself into.

Why Buy in Bulk?

Recently, I was asked to supply four, yes four, bolts for a prospective customer.  Now, true, they were LARGE bolts.  Three quarter by nine inches long with a nut and a washer but still…..four.  Because it was a prospect that was sent to me by a friend and they also had the potential of being a future customer more in line with type that we have serviced for over 25 years, bulk buyers, I quoted.  No surprise I didn’t get the order because they didn’t realize the cost of only buying four bolts at a time but, there is a reason why those who buy in bulk receive such great discounts.
Bulk.  If buying in bulk wasn’t an industry unto itself, there would be no reason for the Walmart’s, Costco’s and Sam Clubs.   Problem is, the Walmart’s, Costco’s and Sam Clubs have been around so long that there are a lot of people who don’t remember when they didn’t exist.  They don’t know that when this Big Box type of storefront came along, those that started to patronize them were willing to sacrifice service and sometimes quality, which up til then was the best thing that a company/store could offer it’s customers, for price.  But at that time, people knew what they were getting and what they were giving up.  They knew that to get lower prices they were going to have to look for items themselves and otherwise sacrifice service that the company/store would normally pay product knowledgeable employees who would assist them with their purchases and make their shopping experience much more enjoyable.  For a short period of time, consumers had a choice.  Service or price.
Now, twenty years later, those days are hazy. The concept that companies would save on expenses by employing fewer people and allowing the consumers would do the labor that otherwise long term employees would do for them in order to pass the savings on to customers is long forgotten.  Younger customers don’t understand why they cant get the same 10% above cost discounts that Big Box offer and still get the quality service that higher priced products provide.  That there are business costs involved in hiring and training employees and sales personnel and unfortunately, those costs always are passed down to the consumer if the company is to remain solvent and healthy.

When I first started in the fastener industry in the early 80?s, selling self tapping zip screws and tek screws, there were three very clear layers of distribution.  Importers, who brought the product from overseas who sold to Distributors who repacked the product into 200 pound kegs or 50 pound cases and sold to Contractors and Hardware Stores who sold 4 bolts.  In order to sell four bolts, they have to pass through three shipping departments (including freight charges) and billing departments in order to get to the consumer. But when you buy in bulk, 50 pound cases or more, those shipping and billing costs are distributed and shared throughout maybe 20,000 screws and not just 4.
There is a good reason why four bolts are so expensive.
There is a value in buying in bulk.

What Are Your Screws Called?


The Round Washer Head design, which can also beidentified as wafer head screws, K-Lathe screws and modified truss screws, could quite possibly be the most multipurpose head design offered. It combines the benefits of the Pan Head design but has an attached washer built on to the head to increase head diameter.  This helps prevent overdriving in softwoods. General cabinet assembly, installation, hinges, metal drawer slides, wooden drawer guides, attaching lights and brackets are just a few applications where the Round Washer Head design is used. The addition of the washer provides maximum bearing surface to allow for "overdriving" the screw to tighten those stubborn joints easily. These Fasteners are also self tapping screws in that they tap their own mating threads and do not need pre threaded inserts like machine screws. It was originally designed for the construction industry to attach wood lathe and metal framing to 20 to 25 gauge steel studs  They also can be known as  plymetal because they can be used to attach plywood to metal. Thebig wafer head sinks into the plywood and has a large bearing surface. The length is measured from the top of the head.
They are available in Philips drive  as well as square drive, which is At times referred to as Robertson drive.  They are available in stainless and well as carbon steel and with plain or painted heads.
Also known as:
Round Washer Head Needlepoint (zip screws) or Self-drilling (Tek Type) Screws
Wafer Head Needlepoint (zip screws) or Self-drilling (Tek Type) Screws
K-Lathe Screws
Modified Truss Needlepoints (zip type) or Self-Drilling (Tek Type) Screws
Sharp point - zip screws - or self drilling - tek type - screws, these screws are also self-tapping screws as they tap their own threads in to the materials they are used with and do not need to be used with a pre-threaded mate such as a nut or insert.
