A Comprehensive Guide to Quick Release Plate Screws
1. Definition and Core Function
A quick release plate screw is a specialized fastener used to connect a camera (or other imaging equipment like camcorders) to a quick release plate. The quick release plate, in turn, attaches to a tripod head, enabling photographers to rapidly mount or dismount the camera from the tripod—eliminating the need to repeatedly adjust tripod screws, thus saving time and improving shooting efficiency, especially in dynamic scenarios (e.g., sports photography, wildlife shooting).
2. Common Types
2.1 By Thread Specification
1/4-inch UNC (Unified National Coarse): The most widely used type, compatible with most consumer cameras (DSLRs, mirrorless cameras, compact cameras) and small camcorders. Its thread pitch is 20 threads per inch, and it is the standard screw size for most camera bottom mounting holes.
3/8-inch UNC: Designed for professional heavy-duty equipment, such as large-format cameras, professional video cameras, or heavy tripod heads. It has a thread pitch of 16 threads per inch and offers higher load-bearing capacity (usually 10-20kg, compared to 3-5kg for 1/4-inch screws).
2.2 By Material
Metal Screws: Made of stainless steel, aluminum alloy, or brass. They are durable, corrosion-resistant, and have strong load-bearing capacity, making them suitable for long-term use and heavy equipment. Stainless steel screws are the best choice for outdoor shooting (resistant to rain and humidity).
Plastic Screws: Lightweight and low-cost, but with low strength and poor durability. They are only suitable for lightweight compact cameras or temporary use (not recommended for professional shooting or heavy equipment, as they may break or strip).
3. Usage Precautions
Avoid Over-Tightening: Use moderate force when tightening the screw. Over-tightening may strip the camera's bottom mounting hole (plastic or aluminum) or damage the screw threads, making future use impossible. Most screws have a "stop" design—stop when you feel slight resistance.
Check Regularly for Wear: Inspect the screw threads and the camera's mounting hole for wear (e.g., flattened threads, cracks) before each use. Worn screws may cause the camera to loosen or fall, leading to equipment damage.
Keep Clean: Remove dust, sand, or debris from the screw threads and the mounting hole regularly. Foreign matter can cause thread jamming or wear during installation/removal. Use a dry cloth or a soft brush for cleaning (avoid using water or oil, which may corrode metal).
Match Sizes Correctly: Never use a 3/8-inch screw on a camera with a 1/4-inch mounting hole (or vice versa). Forcing an incompatible screw will damage the camera's mounting hole permanently. If unsure, check the camera's user manual for the specified screw size.
4. Purchase Suggestions
Prioritize Compatibility: Confirm the camera's mounting hole size (1/4-inch or 3/8-inch) and the quick release plate's screw hole size before purchasing. Most quick release plates (e.g., from Manfrotto, Benro) come with a replaceable screw, but it’s best to buy a matching screw if the original is lost.
Choose High-Quality Metal: Opt for stainless steel or hard aluminum alloy screws. Avoid cheap plastic screws, especially if you use a heavy camera (e.g., a DSLR with a telephoto lens).
Consider Brand Reliability: Purchase screws from well-known tripod/photography accessory brands (e.g., Manfrotto, Peak Design, Benro). These brands have strict quality control, and their screws meet industry standards (e.g., accurate thread size, consistent material thickness).
Check for Anti-Slip Design: Some high-end screws have a knurled (textured) head or a rubber grip, making it easier to tighten/loosen by hand (no need for a tool, which is convenient for on-site adjustments).
