At a Glance
- Arrow part number: 276
- Leg length: 3/8" (10 mm)
- Crown: 7/16"
- Duty: light duty, thin wire
- Finish: electro-galvanized
- Count: 5,000 (5 packs of 1,000)
Why Choose These Staples
JT21 3/8 staples have the longest leg in the JT21 line. That extra length grips better in thicker fabric, padding and softwood than the 1/4" and 5/16" sizes, while the thin wire is easy for a light duty staple gun to drive.
The electro-galvanized finish helps the staples resist rust in normal indoor use. Each pack of 1,000 is easy to keep in a toolbox, and you can open one pack at a time. Review your project list, then contact us for availability.
Compatible Tools
These staples fit the Arrow JT21CM, the JT21 and JT21M, and the Arrow T27, JT27 and TT21. They won't fit T50 staple guns, which use a heavier staple. Review your tool's label to confirm the fit, and contact us if you aren't sure.
Uses
- Home repairs and household projects
- Upholstery and re-covering chair seats
- Crafts, signs and bulletin boards
- Fastening fabric, screening and cardboard to wood
- Holding light plastic sheeting, felt and poster board in place
For outdoor work, heavy lumber or roofing, choose a heavier staple and tool. These are made for light materials, mostly indoors.
Choosing the Right Size
The JT21 line comes in 1/4", 5/16" and 3/8" legs, and Arrow JT21 3/8 staples are the longest of the three. Use 3/8" for thicker or softer material, 5/16" for everyday jobs, and 1/4" for thin material or hardwood. See the JT21 5/16" size and the JT21 1/4" size. A good rule: the staple should pass through the top layer and sink at least as deep again into the base.
