140/12 - Staples

140/12 Staples (Type 140) — Overview

140/12 staples are a popular flat-wire staple format used with compatible staple guns and tackers for fast, tidy fixing. This listing covers Type 140 staples with a 12 mm leg length, supplied in a convenient bulk pack for regular use. They’re commonly chosen where you want a secure hold with a low-profile finish, helping materials sit neatly against the surface.

Because staple compatibility depends on the tool, always match the staple type (140) and leg length (12 mm) to your stapler/tacker’s specification before ordering. If you’re replacing an existing staple, check the markings on the old staple strip or your tool manual for the supported staple series.

Key Bullet Points

• Staple type: 140 series (flat-wire format)
• Leg length: 12 mm
• Bulk quantity: supplied as a large pack for fewer changeovers
• Neat finish: flat-wire profile helps materials sit flush
• Everyday versatility: suited to many light-to-medium fastening tasks with the right tool and substrate

Typical Uses

• General workshop and site fastening where Type 140 staples are specified
• Fixing sheet materials, membranes, and similar flexible coverings (tool/substrate dependent)
• Light joinery, fitting-out, and maintenance tasks requiring a clean staple line
• Packaging, display, and temporary fixing jobs where staples are preferred over nails or pins

140/12 Staples — Full Product Guide

Introduction: Choosing the right staple is about more than just length. The staple series (or “type”) determines the crown shape and wire profile, which must match your tool’s magazine and driver. 140/12 staples combine a widely used Type 140 format with a 12 mm leg length, making them a practical option for users who need a dependable staple for compatible tackers.

How It Works

In a compatible staple gun or tacker, each staple is driven from the magazine and pressed through the top material into the base substrate. The legs penetrate and hold by friction and mechanical grip. A flat-wire staple profile can help spread holding force across the crown, supporting a tidy, even finish along the staple line.

For best results, select a leg length that provides adequate penetration into the base material without over-driving. If the staple is too short, it may not hold securely; too long, and it may not seat properly or could protrude depending on the substrate.

Materials and Construction

This product is supplied as Type 140 staples in a 12 mm leg length. Staples in this category are commonly produced as flat-wire staples intended for use in staple guns/tackers that specify the 140 series. Always confirm the staple series and length required by your tool.

Tool Compatibility (Important)

Staple type must match your tool. “140/12” indicates the staple series and leg length, but different tools accept different staple families (for example, 140 vs other series). Before purchase, check:

• Your tool manual or manufacturer specification for supported staple types
• The staple size markings on the tool body (many tackers list compatible series/lengths)
• The staple you are currently using (compare type and leg length)

If you’re unsure, note your tool model and the staple type/length you need and contact your supplier for confirmation.

Floor Type Compatibility

These staples are designed for use with staple guns/tackers rather than as a flooring-specific fixing. Suitability depends on the application and the base material you are fastening into. Always test on an offcut first to confirm seating and holding strength.

Health and Safety

• Wear eye protection when loading and operating staple guns/tackers.
• Disconnect power/air supply (or engage safety lock) before clearing jams or reloading.
• Keep hands clear of the firing area and never point the tool at yourself or others.
• Use the correct staple type and length to reduce the risk of jams and misfires.

Ideal Applications and Use Cases

140/12 staples are often selected for repeat fastening tasks where speed and consistency matter. With the correct tool and substrate, they can be used for:

• Fixing flexible sheet materials and coverings
• General maintenance and fitting tasks
• Workshop assembly where staples provide a quick mechanical hold
• Packaging and display work requiring a clean, low-profile fastener

As with all staples, performance depends on the base material (e.g., softwood vs hardwood) and the tool’s driving power.

Maintenance, Cleaning and Care

Staples themselves require no maintenance, but good tool care improves results:

• Keep the magazine clean and free of debris to reduce feeding issues.
• Use only the staple type specified for your tool to avoid jams.
• Store staples in a dry place to keep them in good condition for smooth feeding.
• If you experience inconsistent driving depth, check tool settings and test on scrap material.

Case Study (Practical Example)

Scenario: A maintenance team needs a reliable staple for routine fixing tasks using a Type 140-compatible tacker. By standardising on 140/12 staples, they reduce downtime from frequent reloading and keep a consistent fastener on hand for day-to-day jobs. A quick test on the intended substrate confirms the staple seats cleanly and holds as expected, helping the team complete repetitive tasks efficiently.

Who Is It For?

• Facilities and maintenance teams using Type 140-compatible tackers
• Workshops and tradespeople who prefer bulk staple packs for regular use
• DIY users who have confirmed their tool accepts 140 series staples in 12 mm length
