Introduction: Why the Tiny 1 4 20 Screw Deserves Big Attention
When you think about camera gear, lenses, tripods, and memory cards usually steal the spotlight. Yet, one of the most critical components is often overlooked – the humble 1 4 20 camera screw. This tiny fastener holds your camera to a mount, a bracket, or a housing, keeping it steady while you capture the perfect shot. Miss the right screw, and you risk a wobble, a loose connection, or even a cracked sensor.
In this guide we’ll break down everything about the 1 4 20 camera screw: what the numbers mean, which materials work best, how to pick the right length, and practical tips for installation. By the end, you’ll be able to choose, install, and maintain these screws with confidence – no more hunting through junk drawers or buying the wrong part.
Understanding the 1 4 20 Specification
What Does “1 4 20” Mean?
The designation “1 4 20” is a standard thread size used across many camera brands. It translates to:

- 1/4 inch diameter: The outer diameter of the screw shank.
- 20 threads per inch (TPI): The pitch of the thread, meaning there are 20 threads in each inch of length.
This combination provides a strong, yet compact, fastening point that can handle the torque needed for most camera mounts.
Why This Size Became the Industry Standard
Manufacturers adopted the 1 4 20 thread because it balances strength with a small footprint. It’s large enough to resist stripping, yet small enough to fit into lightweight camera bodies. Most DSLR, mirrorless, and many action cameras use this thread for their tripod sockets, making it the go‑to choice for accessories.
Materials and Finishes: Picking the Right Screw for the Job
Stainless Steel – The Outdoor Champion
If you’re mounting a camera in a garden, on a balcony, or in any environment exposed to moisture, stainless steel is your best bet. It resists rust and corrosion, ensuring the screw stays tight for years.

Brass – Gentle on Sensitive Equipment
Brass screws are softer than steel, which means they’re less likely to damage delicate camera threads. They’re ideal for indoor studio rigs or high‑end mirrorless cameras where the mounting plate is made of lightweight alloys.
Coated Screws – Adding an Extra Layer of Protection
Some screws come with a black oxide or zinc coating. These finishes add corrosion resistance while giving a sleek look. They’re perfect for visible mounts on video production rigs where aesthetics matter.
Choosing the Correct Length: Avoiding Over‑ and Under‑Threading
Measuring the Needed Depth
Most camera bodies have a recessed socket that’s about 4‑6 mm deep. A 10 mm (about 3/8 inch) screw is a safe default for most applications. However, if you’re using a larger bracket or a heavy‑duty mount, a longer 12‑14 mm screw may be required.

Common Lengths and Their Uses
- 6 mm (¼ inch): Tiny accessories like lens caps or small LED panels.
- 10 mm (⅜ inch):** Standard for most tripod heads and basic mounts.
- 12‑14 mm (½ inch):** Heavy rigging, motorized gimbals, or security camera housings.
Practical Tip: The “Fit‑Check” Method
Before you tighten, insert the screw gently until you feel resistance. If it bottoms out before the head sits flush with the mounting surface, the screw is too long. If you can keep turning it without resistance, it’s too short.
Tools of the Trade: What You Need to Install a 1 4 20 Camera Screw
Precision Screwdrivers
A small flat‑head or Phillips screwdriver that fits the screw head is essential. Many camera screws use a tiny Phillips #0 or a slotted head. Keep a set of both handy.
Torque Wrenches for Professionals
In high‑end video production, a torque wrench set to 0.5–1 Nm prevents overtightening. Overtightening can strip the threads or crack the camera’s internal chassis, especially on lightweight mirrorless bodies.
Magnetic Pick‑Ups and Storage
Because these screws are tiny, a magnetic tip or a small parts tray keeps them from disappearing into the floorboards. Consider a tiny “screw keeper” that clips onto your camera strap.
Real‑World Applications: Where the 1 4 20 Screw Shines
DSLR and Mirrorless Camera Mounts
Every DSLR you own probably has a 1 4 20 tripod socket. Whether you’re using a standard tripod, a gimbal, or a wall mount, the same screw secures the camera to the accessory.
Security and Trail Cameras
Outdoor security cameras often use a 1 4 20 screw to attach to brackets or pole mounts. The Wildgame Innovations Trail Camera User Manual even recommends stainless steel 1 4 20 screws for long‑term durability.
Custom Rigs and DIY Projects
Enthusiasts love building custom rigs for wildlife photography, time‑lapse, or live streaming. A 1 4 20 screw can hold a small LED panel, a microphone boom, or a battery plate. Just remember to match the material to the environment to avoid corrosion.
Special Cases: Mounting on Vehicles
When mounting a camera on a car roof or a motorcycle, you’ll often need a longer 12‑14 mm stainless steel screw paired with a lock washer to resist vibration. Check out our guide on Mounting A Camera On A Motorcycle for additional vibration‑damping tips.
Maintenance and Troubleshooting
Spotting Wear and Tear
Regularly inspect the screw head and threads. If the head becomes rounded, replace the screw – a stripped head can’t be tightened properly.
Dealing with Stripped Threads
If you notice the screw turning without gaining tension, the internal thread may be stripped. Use a thread‑repair kit (e.g., Helicoil) or replace the mounting plate if possible.
Keeping a Spare Stock
Because 1 4 20 screws are inexpensive, keep a small box of assorted lengths and materials in your camera bag. Losing a screw in the field is common, and having a spare saves a photo shoot.
Buying Guide: Where to Find Quality 1 4 20 Camera Screws
Online Retailers
Large marketplaces like Amazon and B&H Photo sell multi‑packs of 1 4 20 screws in various lengths and finishes. Look for packs that specify “precision threads” and include a small screwdriver.
Local Camera Shops
Independent camera stores often stock a few spare screws for popular models. The advantage is you can test the screw in‑store before buying.
Specialty Fastener Suppliers
If you need a custom length or a unique material (e.g., titanium), specialty hardware suppliers can mill a screw to your exact specs. This is common for high‑end cinematography rigs.
Conclusion: Master the 1 4 20 Camera Screw and Never Miss a Shot
The 1 4 20 camera screw may be small, but it’s a cornerstone of reliable camera mounting. By understanding the thread size, selecting the right material and length, using proper tools, and keeping spares on hand, you eliminate one of the most common sources of equipment failure. Whether you’re shooting a wedding, setting up a backyard security system, or tracking wildlife, the right screw ensures your camera stays exactly where you want it – steady, secure, and ready to capture the moment.
Frequently Asked Questions
What does the “1 4 20” designation stand for?
It indicates a 1/4‑inch diameter screw with 20 threads per inch, the standard size for most camera tripod mounts.
Can I use a 1 4 20 screw on a smartphone camera mount?
Only if the mount specifically includes a 1 4 20 threaded socket. Most phone mounts use a ¼‑20 adapter or a proprietary clamp.
Is stainless steel always the best choice?
Stainless steel is ideal for outdoor or humid environments because it resists rust. For delicate indoor rigs, brass may be gentler on the camera’s internal threads.
How do I prevent overtightening?
Turn the screw until you feel resistance, then stop. For professional rigs, use a torque wrench set to 0.5–1 Nm.
What length screw should I use for a heavy‑duty security camera?
Typically a 12‑14 mm stainless steel screw with a lock washer provides enough holding power for heavy mounts.
Can I replace a missing 1 4 20 screw with a different size?
No. Using a different thread size can damage the camera’s mounting hole. Always replace with the exact 1 4 20 specification.
