10+ Service Parts Every Oil Rig Operation Needs to Have on Hand

When you're drilling miles into the Earth, the last thing you need is a critical part failure with no backup in sight. A well-stocked inventory of oil rig parts can mean the difference between smooth operations and costly, potentially catastrophic delays.

Here are the essential oil rig components every operation should stock to stay ahead of failures.

Oil and Gas Fasteners: Overlooked but Essential

We’ll start with a recommendation (and shameless plug) to not lose sight of the small components. Large machinery and vehicle parts get much of the attention (more on those later), but the reality is that oil and gas operations can’t function without the small fasteners that enable those parts to perform

When taking your inventory, don’t forget to inspect things like bolts, screws, studs, washers, nuts, clamps and brackets. Without them, you’ll experience complications with structural integrity, shortened equipment life and failures, and extended downtimes that result in less profitable operations. So consider this an instance where you should sweat the small stuff.

Now for the plug. Many suppliers don’t carry the small-quantity, hard-to-source service parts that many big oil and gas vehicles or machines need to run. At Wilson-Garner, that’s our specialty. We manufacture low-volume, hard-to-find, and even custom fasteners for oil and gas vehicles, all right here at our plant in Harrison Township, Michigan. So if you need a specialty bolt, stud, or screw for your service vehicle, don’t hesitate to contact us.

Okay, plug over.

Other Important Service Parts for Oil & Gas Equipment

Please understand that we don’t supply all of the service parts listed below at Wilson-Garner. As stated above, we focus mainly on custom or hard-to-find fasteners for oil and gas service vehicles. However, we’re well-versed in the industry enough to recommend some of the other parts you’ll want to have on hand besides fasteners.

Service Parts for Mud Pumps

Oil rigs rely heavily on mud pumps, which are essential for drilling operations. These pumps circulate drilling fluid to cool and lubricate the drill bit, remove cuttings, and stabilize pressure in the wellbore.

Given their crucial role, having these spare mud pump parts readily available is a must:

1. Liners and pistons – High-pressure, high-wear parts that require regular replacement to maintain mud pump efficiency.
2. Valve assemblies – Ensure proper flow control and pressure management, preventing sudden failures.
3. Expendable fluid end parts – These components, including gaskets, seals, and O-rings, maintain optimal pump performance and prevent leaks.
4. Place bolts – These specialized, self-locking fasteners provide superior resistance to drilling vibration — up to seven times more than traditional hex head cap screws — making them a top choice for securing pump skid mounts, ensuring tight structural connections, and preventing loosening in high-impact areas. We DO supply Place bolts at Wilson-Garner if you’re looking for them.

Heavy Machinery and Structural Service Parts

From derricks to drill floors, oil rig structures are subjected to immense stress. Keep a stockpile of these fasteners and reinforcement parts to ensure operational integrity and worker safety.

5. High-strength oil and gas fasteners – Used in critical connections, high-strength bolts, studs, and screws must withstand extreme loads, corrosive environments, and high vibrations.
6. Bearings and bushings – Vital for reducing friction in rotating machinery and preventing premature wear.
7. Hydraulic hoses and fittings – Ensures smooth fluid movement in hydraulic systems so there are no leaks or pressure failures.

Heavy-duty Vehicle Service Parts

Often forgotten about, oil rigs rely on heavy-duty trucks for transporting equipment, supplies, and personnel across rugged terrains.

Have these truck components on hand to prevent unexpected delays:

8. Brake pads and rotors – Critical for vehicle safety and performance in challenging environments.
9. Fuel filters and pumps – Ensures a clean fuel supply, preventing engine damage and improving efficiency.
10. Suspension components – Shocks, struts, and springs reduce drilling vibration and offer stability for rig transport vehicles.
