Staples pack Rapid Tools 40109514 — type 140 flat wire, 8 mm leg, 970 staples

Rapid Tools 40109514 is a pack of 970 flat-wire type 140 staples with an 8 mm leg length. Made from galvanized steel, these staples are designed for use with compatible manual and electric staplers that accept 8 mm leg type 140 staples. The flat-wire design and larger contact area help secure thin materials such as insulation, thin plastics, cardboard and carpets.

Advantages

Galvanized finish improves corrosion resistance for longer storage and use. Precision-cut legs ensure consistent penetration and reliable fastening, while the flat-wire shape provides a broader holding area against the work surface. Diverging points send the leg tips in opposite directions to increase the holding strength in soft or layered materials.

Suitable for

• Fastening insulation material to battens or frames
• Securing thin plastics and vapor barriers
• Attaching thin cardboard or protective sheets
• Fixing carpets or carpet underlay in place
• General-purpose stapling in workshops, offices, and homes

When it may not be suitable

These 8 mm leg staples are intended for medium to thin materials; they may not provide sufficient penetration or holding in thick or dense materials such as thick timber, heavy fabrics, or multiple stacked boards. For heavy-duty construction, insulation with thick supports, or very hard substrates, choose longer-leg or heavy-duty staples designed for those specific applications.

Key specifications

• Staple type: flat-wire, diverging points
• Leg length: 8 mm
• Material: galvanized steel
• Quantity: 970 staples per pack
• Gauge: 140 (flat-wire profile)

How to use

Load the pack into a compatible stapler that accepts type 140, 8 mm leg staples following the stapler manufacturer’s instructions. Position the stapler over the material to be fastened, apply firm, even pressure and trigger the stapler. For layered or soft materials, place staples at regular intervals to distribute holding force and use the diverging point feature to improve grip by angling into the substrate.

What to consider before purchase

• Confirm your stapler accepts type 140 flat-wire staples and 8 mm leg length
• Check whether the materials you intend to fasten are suitable for 8 mm penetration
• Consider corrosion resistance needs—galvanized finish offers basic protection

Usage recommendations

Use these Rapid Tools flat-wire staples for medium-depth stapling of insulation, thin plastics, cardboard and carpets. Place staples evenly and, where possible, test a small area first to ensure sufficient hold without over-penetration.
