While a staple may look pretty straightforward at first glance, there is more than meets the eye. As mentioned, staples come in various sizes to properly fit different sized staplers. That means, the crown and/or the legs may vary in length. The longer the leg, the more the staple can push through. As you could guess, the teeth help pierce the objects you're stapling.
The standard sized staple is typically 1/4" long in leg length. However, other lengths include 3/8”, 1/2", 5/8”, 3/4”. These versions are longer and thicker, catering to larger paper stacks and bulkier objects in heavy duty staplers. Most of our staples are made from high carbon steel wire that reduces jamming, which is great for those avid staplers out there. Additionally, staples come in full strips (210 staplers) or half strips (105 staples), depending on which type of stapler you own.
It doesn't stop there, either. Upon staple size, there are also five different varieties of Bostitch staples: standard, mini, PowerCrown™, EZ Squeeze™, and Premium Heavy Duty. So, what's the different between each type?
First, our standard staples are made to fit any of our standard staplers, while our Premium Heavy Duty staples are specially created with finely honed chisel points to deliver maximum penetration in heavy duty staplers. Additionally, the PowerCrown™ staples have a special peak in the crown that is flattened during stapling. It then forces the legs outward for further support in the stapler during operation. The EZ Squeeze™ take on the same design, but are sized to fit exclusively in the EZ Squeeze™ staplers.
When shopping for staples, it's best to first choose which type is compatible with your existing stapler, and then choose the leg length.
