Air Nail Guns

About Air Nail Guns

Air nail guns, also known as pneumatic nailers, are essential power tools that drive nails into timber, board, and other materials using compressed air. These professional-grade tools dramatically increase productivity on site, allowing tradespeople to complete fastening tasks in a fraction of the time required for manual nailing. Whether you're framing a new build, installing joist hangers, fixing skirting boards, or laying flooring, there's an air nail gun designed specifically for your application.

Our range includes specialist models from industry-leading brands including DeWalt, Bostitch, and Makita. From heavy-duty framing nailers that handle first and second fix carpentry to precision brad nailers for delicate trim work, each tool is engineered for reliability and consistent performance. We stock 16 gauge finish nailers for architrave and mouldings, 18 gauge brad nailers for cabinet making, 23 gauge pinners for fine joinery, and robust framing nailers for structural work. Many models feature depth adjustment, tool-free jam clearing, and sequential or bump firing modes to suit different working styles.

Air nail guns require connection to an air compressor via a standard air hose, making them ideal for workshop environments and construction sites where compressed air is readily available. Their simple pneumatic operation means fewer moving parts compared to cordless alternatives, resulting in lower maintenance costs and exceptional durability even under demanding professional use.

Jargon Buster

• Gauge: The thickness measurement of the nail; lower numbers indicate thicker nails (e.g., 16 gauge is thicker than 23 gauge). Different gauges suit different applications, from heavy structural work to delicate finishing.
• Sequential Firing Mode: Also called single-shot or restricted trigger, this safety mode requires the nose contact to be engaged before each trigger pull, offering maximum control and precision for careful positioning.
• Bump Firing Mode: Also known as contact trip, this mode allows rapid-fire nailing by holding the trigger and bumping the nose contact against the work surface, significantly increasing speed on repetitive tasks.
• Magazine Capacity: The number of nails the gun can hold at once before reloading. Typical capacities range from 50 to over 100 nails depending on the model and nail size.
• Operating Pressure: The air pressure (measured in PSI or bar) required to operate the tool effectively. Most air nail guns operate between 4-8 bar (60-120 PSI), adjustable via your air compressor regulator.
• Depth Adjustment: A mechanism allowing you to control how deep the nail is driven into the material, from sitting flush to countersunk below the surface for filling.

How to Choose the Right Air Nail Guns

Application Type: Match the nailer to your primary work. Framing nailers handle structural carpentry with 50-90mm nails, finish nailers suit architrave and skirting with 30-65mm nails, brad nailers work for delicate trim with 15-50mm brads, and pinners offer near-invisible fixing for mouldings with 10-30mm pins.

Nail Gauge and Length Range: Consider the gauge (wire thickness) and length range the tool accepts. Heavier construction requires lower gauge numbers (thicker nails), while fine finishing needs higher gauge numbers. Check that your chosen model accommodates the nail sizes you use most frequently.

Magazine Style and Angle: Straight magazines offer better sightlines for precision work, whilst angled magazines (typically 30-34 degrees) provide improved access into corners and tight spaces. Coil-fed nailers hold more fasteners but are bulkier, whilst strip-fed models are more manoeuvrable.

Air Consumption and Compressor Compatibility: Check the tool's CFM (cubic feet per minute) or litres per minute air consumption against your compressor's output. Ensure your compressor can maintain the required operating pressure during continuous use, particularly important when running multiple pneumatic tools.

Weight and Ergonomics: If you'll be working overhead or for extended periods, weight becomes crucial. Look for well-balanced tools with comfortable grips and easy access to depth adjustment. Features like tool-free jam clearing save valuable time on site.

Brand and Serviceability: Stick with established brands like DeWalt, Bostitch, and Makita that offer readily available spare parts, service centres throughout the UK, and comprehensive warranties. Professional-grade tools withstand daily site use far better than budget alternatives.

Safety Information

Air nail guns are powerful tools that demand respect and proper handling. Always wear appropriate safety glasses or goggles to protect against ejected fasteners, wood splinters, and ricochets. Hearing protection is recommended during extended use, as pneumatic tools can exceed 85dB.

Never bypass safety mechanisms or disable the nose contact trigger. Always disconnect the air supply before clearing jams, performing maintenance, or adjusting the tool. Keep your free hand well away from the nailing area and maintain secure footing, especially when working at height or in awkward positions.

Follow HSE guidelines for working with compressed air equipment and pneumatic tools. Ensure all air hoses and connections are in good condition without leaks or damage. Never point the tool at yourself or others, even when disconnected. Store tools with the air supply disconnected in a secure location away from unauthorised users.

Check the work surface behind your material to avoid striking hidden cables, pipes, or fixings. When working on site, maintain awareness of others in your vicinity and use sequential firing mode in busy areas to prevent accidental discharge.

Frequently Asked Questions

What size air compressor do I need for an air nail gun?

Most finish nailers and brad nailers work well with a 24-50 litre compressor delivering 6-8 CFM at 90 PSI. Framing nailers require larger compressors (50+ litres) with higher CFM output, particularly for continuous use. Check your specific tool's air consumption specifications and ensure your compressor can maintain pressure during operation.

Should I choose an angled or straight magazine nailer?

Angled magazines (typically 30-34 degrees) excel in tight spaces like corners and between joists, making them popular for framing and general carpentry. Straight magazines offer better visibility of the nail placement point, preferred for precision finishing work. Many professionals own both types for different applications.

How often should I oil my air nail gun?

Add 4-5 drops of pneumatic tool oil into the air inlet before each use, or every few hours during continuous operation. This lubricates internal o-rings and moving parts, preventing premature wear and maintaining consistent performance. You can also install an inline oiler in your air line for automatic lubrication.

Can I use any nails in my air nail gun?

No, you must use nails specifically designed for your model's gauge and magazine type. Different manufacturers use various collation methods (wire, paper, plastic) and angles. Using incorrect fasteners causes jams, misfires, and potential tool damage. Always check compatibility before purchasing nails.

What's the difference between 16 gauge and 18 gauge nailers?

16 gauge nailers fire thicker nails (1.6mm diameter) suitable for heavier trim, skirting boards, and door casings where greater holding power is needed. 18 gauge brad nailers use finer nails (1.2mm diameter) that leave smaller holes, ideal for delicate mouldings, beading, and cabinet assembly where minimal surface damage matters.
