Custom Knobs Manufacturing and Machined Hardware
DEK machines control and instrument knobs, knurled thumb knobs, hand wheels, T-handles, L-handles and pull handles from 6061 and 7075 aluminum, brass, 303 and 316 stainless, titanium and Delrin.
These are the parts a user touches, so the specification is half function and half feel: bore fit, set-screw or collet grip, knurl pitch, edge radii and a durable finish. They are listed in our custom CNC machined parts catalogue, with Swiss-turned features to ±0.003 mm.
Types of Knobs and Handles We Machine
Knobs, handles and matching hardware turned and milled from aluminum, brass, stainless, titanium and Delrin bar.
-
Custom Control KnobsPointer, skirted and dial knobs for switches, encoders and potentiometers. -
Knurled Knobs CNC TurnedStraight, diamond or helical knurls, plain or with a threaded stud. -
Machined Aluminum KnobsAudio, instrument, camera and lab equipment knobs, anodized in color. -
Hand Wheels & Thumb WheelsWheels and adjustment dials with engraved or laser-marked graduations. -
T-Handles & L-HandlesT-handles, L-handles and lever handles for clamps, valves and latches. -
Pull & Rack HandlesPull handles, bar handles and rack handles for enclosures and cases. -
Matching Machined HardwareThumb screws, feet, bezels, end caps and collars to match the knobs.
Materials, Processes & Tolerances for Knobs
How we turn, mill and finish knobs and handles: the materials, the machines, the specs we hold and the finishes.
Design Tips for Custom Knobs and Handles
Five rules that decide how a knob fits its shaft, grips in the hand and holds its color after anodizing.
-
Define the Shaft Fit
Give shaft diameter, D-flat depth, length and fixing; "6 mm bore" without the flat or set-screw position leaves the fit undefined.
-
Match Knurl Pitch to Size
Use 0.8 mm diamond on 10–25 mm knobs and 1.0–1.2 mm on larger ones. See knurl vs spline.
-
Radius Every Gripped Edge
Add a 0.5–1.0 mm edge radius on gripped edges; a sharp anodized edge feels like a blade and chips.
-
Plan for Anodize Build-Up
Anodizing adds 10–15 µm per surface and darkens a knurl; if color matters, approve a sample before production.
-
Keep 2 mm Bore Walls
Hold the wall between bore and OD at 2 mm minimum in aluminum so set-screw torque does not distort the knob.
What to Call Out on Your Drawing
-
Shaft and Fixing
Shaft diameter and D-flat, then set-screw (M2–M6), collet or press fit; we match the bore to H7.
-
Knurl Style
Straight, diamond or helical to DIN 82, with pitch from 0.5 to 1.6 mm and the diameter it runs on.
-
Finish and Color
Blasted, anodized color or polished, plus laser-marked legends; we can approve a color sample before the run.
-
Quantity and Batch Size
From one prototype with no MOQ to a matched production set of knobs, handles and thumb screws shipped together.
Applications & Industries
Custom handles machining and knob work for audio, camera and instrument makers, electronics front panels and rack handles, and autoclavable medical knobs.

Why DEK for Machined Aluminum Knobs
Cosmetic parts made by a shop built for tolerance work, with every process for a matched set under one roof.
-
Knurls True to Bore
The knurl and the bore are cut in one setup on the lathe, so the pattern runs true to the shaft with 0.02 mm OD-to-bore runout.
-
Matched Anodized Colors
Anodized colors are matched against an approved sample, and every batch is photographed before shipment.
-
Processes In-House
Turning, Swiss, milling, blasting, anodizing and laser marking are in-house, so knobs, handles and thumb screws ship together.
-
Certified Quality
Knobs and handles are made under ISO 9001:2015, ISO 13485 and AS9100D certified quality systems, including medical knobs.
Engineer-Reviewed Quotes
