Heavy-Duty Staples for 55 to 85 Sheets

These Stanley Bostitch SB351/25M staples are designed for heavy-duty stapling tasks in office and professional environments. They suit users who regularly bind thick document stacks and require reliable feeding in compatible heavy-duty staplers. The 5,000-staple box supports high-volume workflows without frequent reordering.

Sustained High-Volume Stapling Behaviour

Premium carbon steel wire resists buckling during repeated driving through maximum-capacity stacks. The chisel-point geometry maintains penetration consistency across long runs, reducing jam frequency when the stapler cycles continuously. Leg length of 12 mm is optimised for the 55 to 85 sheet range so each staple clinches cleanly without over-driving or under-driving.

Practical Limits of Half-Inch Leg Length

The fixed 12 mm leg restricts use to stacks between 55 and 85 sheets; thinner bundles may not clinch securely and thicker bundles exceed the staple's clinch capacity. These staples are not suited for light-duty desktop staplers or for binding materials beyond the specified sheet range. Compatibility depends on the stapler accepting the SB351/25M form factor.

Questions about this item

How much force does the 12 mm leg length require from the stapler when driving through a full 85-sheet stack?

The 12 mm chisel-point legs are made from premium carbon steel to reduce buckling and jamming, giving reliable penetration through the maximum 85-sheet capacity.

Which stapler models accept the SB351/25M staples for the rated 55- to 85-sheet capacity?

These staples are engineered for heavy-duty staplers that support a 12 mm leg length and 55- to 85-sheet capacity; check your stapler's specifications for compatibility.

Will the silver carbon-steel finish cause corrosion or marking on older paper archives?

The silver premium carbon-steel construction is designed for clean penetration and does not contain coatings that typically mark or corrode paper over time.
