V-Slot 2020 Series
V-Slot 2020 Series is a 20 × 20 mm aluminum extrusion with V-shaped groove edges for compatible wheel-guided motion and modular framing. APW supplies standard and one-side-closed sections in silver or black anodized finishes. Compare the four variants, then send your cut list and mating-part requirements for a quote.

One profile for framing and wheel-guided motion
A 2020 V-slot aluminum extrusion combines a structural member with guide surfaces. The wheel, carriage and connection details determine how it works in your assembly.
V-shaped guide faces
The angled groove edges provide a running surface for matching V-wheels. OpenBuilds explains this framing-and-motion principle in source [2]. Select the wheel and carriage around the actual section.
Adjustable frame connections
Slots accept appropriately sized nuts and fasteners for brackets, plates and peripherals. Check nut seating, bracket location and bolt engagement before ordering hardware.
Open or one-side-closed sections
Choose an open section where all four faces need slot access, or a one-side-closed section where the assembly calls for a continuous outer face. Plan wheel paths and fixing access around that choice.

These four supply options follow the named sections in HTS product data [1]. The source calls its silver versions “White”; here they are labeled silver anodized to distinguish the finish from white paint.

V-Slot 2020 finishes and section details
AI-generated product visualizations for appearance and section comparison only. They are not photographs of delivered goods or manufacturing drawings. Confirm dimensions, wheel interfaces and finish against the selected drawing and agreed sample.
V-Slot 2020 or T-Slot 2020? Start with the interface
Both names can describe a 20 × 20 mm outside section. V-Slot adds angled running faces for matching wheels; a shared outside size does not establish interchangeable nuts, carriages or brackets.
- For wheel-guided travel, match the V-wheel contact profile, wheel spacing and carriage clearance to the selected section.
- For a frame joint, compare the complete groove cavity, nut body and bracket interface rather than thread size alone.
- For a one-side-closed section, orient the closed face so it does not obstruct a required wheel path, fastener or later accessory.

Where a 20x20 V-slot profile fits
The framing-and-motion approach is used in the applications described by OpenBuilds [2]. Select the member size and assembly around your span, moving mass and required stiffness.
- 3D printer frames and motion assemblies
Define the frame envelope, axis travel and wheel carriage together. Specify individual member lengths after resolving the joints.
- Camera sliders
Use matching wheels and a carriage layout suited to the camera arrangement. State the rail span, support positions and moving mass in the inquiry.
- Compact CNC and positioning projects
Use the profile as a framing or motion-system component where the design supports it. The series name alone does not establish machining accuracy or load capacity.
Define the supply before comparing quotations
Specify the open or one-side-closed section, finish color, individual cut lengths, piece counts and destination. Include any requested cutting, drilling or tapping with dimensioned drawings so feasibility and tolerances can be quoted. Price, minimum quantity, packing and lead time are confirmed for the order.
Confirm the profile and mating parts
Use the complete section and accessory drawings to resolve the connection or motion interface. The specifications above describe this four-variant offer, not every manufacturer's 2020 profile.
Identify the section
State standard open or one side closed, silver or black anodized, and the drawing revision or sample reference you are matching.
Check the groove and nut
Compare the opening and internal cavity with the nut's body, insertion method and seating. Check the bracket tabs and bolt engagement as part of the same joint.
Check wheel contact and clearance
Match the wheel geometry and carriage spacing to the guide faces. Check that connectors, panels and the closed side do not interfere with travel.
Define end work separately
A center-hole diameter does not specify a finished thread. Supply the required thread, depth and end preparation on a machining drawing if tapping is needed.

V-Slot 2020 questions
What is V-Slot 2020 Series?
V-Slot 2020 Series is a nominal 20 × 20 mm aluminum profile family with V-shaped groove edges that can guide matching V-wheels while also providing slots for frame connections. This page offers standard open and one-side-closed sections in silver or black anodized finishes.
What is the difference between V-Slot and T-Slot 2020?
The 2020 designation identifies the nominal 20 × 20 mm outside size. V-Slot includes angled guide faces for matching wheels. T-Slot describes a connection-slot system and does not by itself establish those wheel-running faces. Compare the complete drawings before substituting one for the other.
Which V-Slot 2020 variants can APW supply?
APW supplies the four variants compared here: standard open silver, standard open black, one-side-closed silver and one-side-closed black, all anodized 6063-T5. Identify the section layout and color in your quote request; supply terms and delivery timing are confirmed for the order.
What are the slot opening and center-hole dimensions?
For the four sections documented in source [1], the slot opening is 6.2 mm, the V-groove angle is 90° and the center-hole diameter is 4.2 mm. These values are not universal to every 2020 listing. Use the selected drawing to confirm tolerances, cavity geometry and any requested thread preparation.
Will any 2020 nut or V-wheel fit this profile?
Fit cannot be established from the 2020 name or bolt thread alone. Compare the nut body and seating, groove cavity, wheel contact shape, carriage spacing and fastener clearances against the selected drawings. State the accessory or wheel model you need to match when requesting a quote.
When should I choose the one-side-closed version?
Choose it when your layout calls for a continuous outer face on one side. That face changes access for slots and wheel-guided motion, so decide its orientation before defining joints, panels and carriage travel. The published mass is 0.55 kg/m for the closed-side variants, compared with 0.47 kg/m for the standard variants [1].
What lengths and machining details should I request?
Send individual cut lengths and quantities, the required tolerances, finish color and delivery destination. Add dimensioned hole or thread details for any requested drilling or tapping. Feasibility, supply lengths, minimum quantity and processing terms are confirmed in the quotation; this page does not specify a stocked length range.
How much load can a V-Slot 2020 profile carry?
There is no single load rating for the series name. Capacity and deflection depend on the exact section, span, support arrangement, load direction, joints and any moving assembly. The listed mass per meter is a material-planning value, not a structural or motion-system capacity. Provide the application and load arrangement for engineering review.
