I am not a cabinetmaker. I am the person who turns a cabinetmaker’s request into a purchase order. For the last six years, I’ve handled facilities purchasing for a 140-person company, covering three buildings and a small workshop. That means about 190 purchase orders a year, including a steady volume of Hettich hardware: drawer slides, hinges, locks, connector fittings, and the small spares that inevitably go missing before installation day.
My first instinct with Hettich drawer slides was to search the name, pick a product, and ask the technician if it looked right. A November 2023 order ended that habit. We needed 500 mm slides for a run of metal-frame cabinets. I ordered a slide that was clearly marked as Hettich. It was the right length. It was not the right system. The mounting hole pattern was different, so the drawer could not be aligned.
Everyone who touched that order had a different explanation, but the root cause was simple: “Hettich drawer slides” is not a complete specification. This article is the decision process I now use when a project needs drawer slides, connector fittings, or a lock instruction that has to match hardware from Hettich.
Start With the Scenario
There is no one correct Hettich product for every job. I sort incoming requests into three scenarios:
- New cabinetry or complete renovation — nothing is installed yet.
- Existing drawer or cabinet hardware is damaged and needs replacement.
- The job is about finding instructions or spare parts, not buying a full new system.
Scenario 1: Hettich Drawer Slides for New Construction
If you are buying for new cabinets, the project needs more than a category. A Hettich drawer slide can be part of a ball-bearing runner, a wood drawer runner, or a complete drawer system. Each choice affects drawer box construction and side clearances. So before I create a purchase order, I ask for a full specification.
- The exact Hettich product name and product number.
- Nominal slide length and extension type.
- Mounting type for the drawer side and drawer bottom.
- Motion behavior: damping, push-to-open, or standard.
- Any connector or hinge package needed to assemble the surrounding cabinet.
If the quote simply says “drawer slides,” I treat it as incomplete. New construction is the easiest place to be strict, because nobody has installed the wrong slide yet.
Hettich Connector Fittings Deserve a Separate Line
On new jobs, Hettich connector fittings are easy to treat as an afterthought. They are not. Board thickness, drill depth and connecting direction all change the correct part. A connector that works in one cabinet seam may not work in another. I ask the joinery team for the connector specification before I issue a PO.
I have learned to ask what is not included before I ask the price. A quote that lists every component — including connectors — is more transparent and usually costs less in the end. Hidden parts show up later as extra orders and extra labor.
Scenario 2: Replacing Hettich Drawer Slides and Fittings on Existing Cabinets
When the request is “replace,” do not start with product marketing. Start with the old part. The Hettich product number is often stamped into the metal rail or printed on the runner label. If the drawer is still in place, take it out, photograph the rail with a ruler, and write down the numbers you can see. Slide length alone is not enough.
The mistake that changed my process was an order for 18 drawer slides. The slides were the same length as the old ones, and the brand was the same. The mounting pattern was different because the old runner belonged to a different Hettich runner family. The slides arrived; the cabinets stood waiting. That was the last time I approved an order without a product code.
A drawer slide order should be boring. Product name, product number, quantity. The less exciting the order, the easier it is to get right.
Hettich Connector Fittings on Replacement Drawer Fronts
Drawer front replacement is another place where connector fittings get underestimated. The original drawer front may use a Hettich cam-and-dowel connector that has to fit an existing drill pattern. A connector that looks the same in a photo can still differ in cam length, screw thread or depth. Keep the old fitting in a bag until the new part arrives, and match it against the drawing.
Small Items Are Still Orders: Screwdriver Pocket Set (2 pc)
When I prepare a service order, I do not skip the small lines that appear on Hettich spare-parts lists. Screwdriver pocket set (2 pc) is one example. It is a small accessory item, often needed for a lock or connector adjustment. If I treat it as “just two screwdrivers,” the wrong set arrives. If I match the part number from the original instruction sheet, the technician has the right tool and the job gets finished without a return trip. That is the whole difference.
Scenario 3: Door Lock Instructions, Spare Parts, and Loose Components
Another recurring request in our office is phrased exactly like the search query: Hettich door lock instructions. The frustrating part is that there is no single answer sheet for all Hettich locks. A cabinet door lock with a round cylinder cam, a latch-style lock, and a central locking system have different installation sequences.
Before looking for instructions, find the lock’s product identifier. It may be printed on the lock case or on an installation label near the strike. Search that number, not only the words “Hettich door lock instructions.” The same rule applies when you lose a spare part: write down the numbers from the lock body and the instruction sheet before calling a supplier.
If the job includes a lost accessory, make the same identification effort. A screwdriver pocket set (2 pc) might sound generic, but it is ordered against a Hettich product code in many service lists. The code is what makes the spare compatible.
What Is a 10mm Drill Bit in Fraction?
This exact question shows up when a drawing or instruction specifies a 10 mm hole and the person on site is using a fractional drill set.
10 mm equals 0.3937 inches. The closest common fractional drill bit is 25/64 inch, which equals 0.3906 inches. The difference is about 0.08 mm, so 25/64 is normally the right fractional substitute.
Do not default to 3/8 inch for a 10 mm hole. 3/8 inch is 9.525 mm and can be too tight. If the cabinet shop has both metric and fractional sets, use the metric 10 mm bit first. If only fractional bits are available, test the 25/64 bit on scrap material before drilling the finished panel.
Which Scenario Are You In?
When a Hettich request lands on my desk, here is how I decide what to do:
- New cabinet assembly? Quote the exact Hettich drawer slide system and list connector fittings separately.
- Replacing an old slide or drawer front? Remove the old part, find the product number, and order from that number.
- Trying to install or repair a lock? Identify the lock first, then find the matching Hettich door lock instructions or spare accessory.
- Metric drill size is the only unknown? 10 mm is closest to 25/64 inch, but verify the fit before drilling the cabinet.
A good purchase order is transparent. If the vendor can read the exact Hettich product number, the technician can install the part without calling me back. That is the only outcome I care about.
