Search this category by sizeFixing and locating elements are precision-turned parts that lock the position of two components relative to one another with repeatable accuracy — in dies and molds, work-holding fixtures, assembly jigs and machine frames. In this category Ayyıldız Robotics produces 14 families and 154 types: parallel dowel pins (ISO 2338), internally tapped extraction dowels (ISO 8733), conical-tip and threaded-mount locating pins, hex-drive locating pins (SW7–SW17), shouldered rest pins, knurled press-fit guide pins, set screws (DIN 913/914), stop pins, support pins and stop bushings, locating pins, knurled adjusting nuts and adjustable stop studs. We machine them in steel, stainless steel, brass and aluminum, in the ⌀1–20 mm range (the SW-20 caps at ⌀20 mm) on a CNC Swiss-type lathe. As standard we hold m6 for press fits, g6 for guiding/locating, h6/h7 on the pin body, 6g/6H on threads, internal threads from M2.5 to M12 and a 60° centering cone. Beyond standard sizes we also produce to your technical drawing; pricing is by quote.
Across 154 variants the operation mix is 51× thread turning, 27× hex flat milling, 34× axial bore, 11× taper turning, 26× knurling. Parts run 4–86 mm long; the longest, TESA-CPC-20 at 86 mm, still finishes in a single setup.
Tolerances span 8 classes (6H, 6g, H7, g6, h6, h7, h8, m6) and 132 variants carry a DIN or ISO reference. The highest length-to-diameter ratio in the category belongs to TESA-CPC-03 at L/D 5.7 — the slimmest proportion here, still within reach of a conventional lathe.
Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.
Frequently Asked Questions
Parallel dowel pins (ISO 2338) are turned in a single operation on the Goodway SW-20 Swiss-type lathe, chamfered at the ends and brought to the required fit class together with hardness. As standard we produce m6 for press (interference) fits, g6 for sliding/locating fits and h6/h7 for the general pin body. For the extraction type we tap an internal thread (M2.5–M12) per ISO 8733.
Steel, stainless steel (for corrosion and food/medical environments), brass and aluminum. Material is selected according to working load, wear, corrosion exposure and the mating part; just state the application in your request and we will recommend a suitable grade.
Given the bar capacity of the SW-20 Swiss lathe we work in the ⌀1–20 mm range. On critical diameters we target h6/g6/m6 classes, 6g/6H on threads, a 60° centering cone on conical tips; where the geometry allows, ±0.01 mm is targeted. Just note the tolerance and surface requirement on your drawing.
Yes. Alongside the 154 standard types we produce parts to your technical drawing (PDF, DWG/STEP or a dimensioned sketch) with custom shoulders, internal threads, knurls, hex drives or spherical/conical rest tips. We can also reverse-engineer from a sample or drawing.
We have manufactured in Düzce, Türkiye since 2009 and serve both prototype/sample quantities and series orders, without imposing a rigid minimum. Lead time depends on material supply, quantity and part complexity and is stated clearly in the quote. Pricing is by quote.
