Stainless Steel Clevis Rod Ends
Precision CNC-machined stainless steel clevises (yoke ends) in 304, 316L, and 17-4PH. Manufactured to DIN 71752 / ISO 8140 standards or custom drawings with fork, pin bore, and thread machined to your specification.
Product Overview
What Is a Stainless Steel Clevis?
A clevis is the U-shaped forked body with two parallel ears and a threaded shank. It forms part of a pinned mechanical linkage, allowing angular or pivoting movement while carrying tension or push-pull load between two connected parts.
A clevis is not the same part as a clevis pin. The pin is the separate cylindrical component that passes through the aligned holes in the ears and the mating eye. Profab supplies the clevis body and matched pins as a set, or either component separately. See Related Products and the Clevis Kits section below.
Product Range
Types of Stainless Steel Clevis
Profab Machine manufactures stainless steel clevises by CNC machining to customer drawings or standard dimensional specifications, in grade 304, 316, 316L, and 17-4PH, with inch or metric threads and custom fork width and pin diameter.
Steering Clevis
Fits steering drag links and tie rods where the pin runs in double shear. Fork width matched to your steering arm thickness. Available in 17-4PH for high shock-load applications.
Clevis Joint
The general-purpose pinned joint for linkages, tension rods, and actuators. Pairs with our clevis pins, sold together or separately. Left-hand threads available for turnbuckle-style assemblies.

DIN 71752
The German rod end clevis standard for cylinder work. H9 pin bore and 6H thread tolerance classes are specified where the standard designation calls for them. Sizes from G4x8 through G50x96, fine-pitch FG variants.
ISO 8140
Interchangeable mounting dimensions for 10 bar pneumatic cylinder clevises. Short and long versions to match your cylinder model. Mates with CETOP RP102P equipment.
Selection Guide
How to Select the Right Clevis
DIN 71752 sizes are designated by pin diameter and overall assembled length. The table below shows typical dimensions across the standard range, compiled from published stainless clevis catalogs. Confirm the exact dimension for your size at quote.
| DIN Designation | Typical Pin Diameter | Typical Thread | Typical Use |
|---|---|---|---|
| G6x12 | 6 mm | M6 | Small instrumentation and control linkages |
| G8x16 | 8 mm | M8 | Light pneumatic cylinders, sensor linkages |
| G12x24 | 12 mm | M12 | Standard pneumatic/hydraulic cylinder clevises |
| G16x32 | 16 mm | M16 | Medium-duty actuator and steering linkages |
| G20x40 | 20 mm | M20 | Heavier actuator rods, agricultural linkages |
| G32x64 – G50x96 | 32–50 mm | M32–M50 | Heavy-duty hydraulic cylinders, structural rigging |
Clevis Selection Parameters
| Parameter | What to Check | Selection Advice |
|---|---|---|
| Standard | DIN 71752, ISO 8140, or custom drawing | Send your cylinder model or existing part for a mating-dimension check before ordering to a standard. |
| Thread | Internal vs. external, metric/UNC/UNF, coarse or fine pitch, hand direction | Match the mating rod or cylinder thread exactly; a coarse/fine or RH/LH mismatch will not seat correctly. |
| Pin & Fork | Pin diameter, fork width, single vs. double shear | Specify fork width to the mating eye's actual width, not a nominal size, to avoid side load or slop. |
| Retention | Cotter pin, R-clip, circlip, snap ring, or custom cross-hole/groove | Choose based on vibration exposure and how often the joint needs to be disassembled for service. |
| Material | Body, pin, and retainer grade (these can differ) | Match pin and body material in corrosive environments to avoid galvanic pairing issues. |
Material Specification
Choosing the Right Grade
304 Stainless
The baseline grade for indoor automation, humidity, and general washdown environments. Solid stainless construction eliminates thin plating layers that chip or wear away at the pin bore under double-shear movement.
General Industry Indoor Automation316 / 316L
The marine and CIP washdown grade. The 2.0–3.0% molybdenum addition raises chloride pitting resistance significantly above 304, for cylinder clevises and rigging links exposed to salt spray or aggressive sanitizers.
Marine Rigging CIP Washdown17-4PH
The high-strength alloy for high-cycle and heavy-duty applications. Precipitation-hardened to the H900 condition, it reaches tensile strength up to 1,310 MPa, resisting fork spreading under shock and reversal loads.
Heavy Duty High-Load LinkagesApplications
Clevis Joint Solutions By Industries
Profab cuts clevises for the mount each industry actually uses, from cylinder ends to facade rigging. We match grade, thread, and finish to your environment, not to a stock catalog.
Hydraulics & Pneumatics
Cylinder rod ends thread onto our ISO 8140 clevises, sized from G4x8 up to G50x96 with fine-pitch threads where the rod calls for them.
Marine & Rigging
Standing rigging and deck hardware clevises in 316L. Salt spray that kills zinc plating in a season leaves the stainless yoke standing.
Agriculture
Harvester and plough linkages meet fertilizer spray all season. Stainless clevises outlast zinc-plated hardware that fails within one season.
Architecture & Facades
Point-fixed glazing and cable railing terminals. Bright-machined or mirror-polished clevises stay clean on facades where rust bleed would stain the glass.
Clevis Dimensions for Reliable Drop-In Fit
Incorrect mechanical mating creates costly downtime in linkage assemblies. Profab manufactures clevis components with tight dimensional tolerances across pin hole diameter, fork width, and thread pitch. Our precision CNC machining keeps thread engagement to UNF and metric standards without binding, and controls fork spacing to match your mating eye, eliminating axial slop or frame interference. Each clevis rod end is machined to your dimensions for direct, drop-in installation.
Heavy-Duty Clevis Load Capacity and Fatigue Resistance
Dynamic articulation causes fatigue failure and premature joint wear under repetitive mechanical cycles. Profab CNC-machines clevis geometry — fork depth, ear thickness, and pin bore fit — directly from solid 304, 316L, or 17-4PH bar stock to resist fork spreading under peak shock and axial loads. Where a hardened 17-4PH body is specified for extreme-duty service, heat treatment is available through our qualified process network. Smoothly finished pin bores minimize surface friction, reducing rotational wear over the joint's service life.

Common Questions

What is the difference between a clevis and a clevis pin?
A clevis is the U-shaped forked body with two parallel ears and a threaded shank. A clevis pin is the separate cylindrical pin that passes through the aligned holes in the clevis ears and the mating component. They are two distinct parts. Profab supplies both the clevis body and matched clevis pins as a set, or either component separately.
Can you customize clevis dimensions, pin diameters, and thread patterns?
Yes. Profab can customize clevis fork width, ear thickness, pin diameter, and thread style. Our stainless clevis is machined to your drawing for bespoke machinery and OEM integrations.
What surface finish do you provide on stainless steel clevises?
Standard finish is bright machined. ASTM A967 passivation is available as an optional finish. Electropolishing (Ra ≤ 0.4 µm) is available for food-grade or pharmaceutical applications. Surface finish is specified at time of order.
Which standard should I order, DIN 71752 or ISO 8140?
DIN 71752 is the German rod end clevis standard for cylinder rods. ISO 8140 covers interchangeable mounting dimensions for 10 bar pneumatic cylinders, short and long versions. Send your cylinder model and we will check the mating dimensions, then cut the thread pitch and slot the standard calls for.
