Klein Tools 3255TT Broad Head Bull Pin with Tether Hole

SKU CH-T5E1-VGSGX

Broad-head bull pin with tether hole for aligning steel holes and preventing drops

  • Broad head resists mushrooming during heavy alignment work
  • 13 3/4 inch overall length provides extended reach in tight spaces
  • Tether hole enables secure attachment to prevent drops at height
  • Corrosion-resistant finish protects the steel body in harsh environments
  • Includes striking cap for direct hammer impact without damage

Broad Head Bull Pin for Steel Alignment

The Klein Tools 3255TT is a broad head bull pin designed for aligning and driving holes in steel structures. Its 13 3/4 inch overall length and 13 inch taper provide the reach and leverage needed for structural steel work. The tether hole allows attachment to a lanyard for drop prevention at height.

Manual Impact Only with Striking Cap

This tool relies entirely on manual striking force applied to the included striking cap; there is no automatic or powered mechanism. The plain round shank and lack of a handguard mean the user must control alignment and absorb vibration directly. Corrosion resistance helps maintain the 5/16 inch point during exposure to job-site conditions.

Tether Ready for Working at Height

The 1/4 inch tether hole is the critical feature for any worker required to secure tools against drops. Without a tether attachment point, this pin cannot comply with common drop-prevention policies on elevated steel erection sites. Buyers who do not need tether capability should consider a standard bull pin without the hole.

Questions about this item

Should I pick the 3255TT or another bull pin model for my kit?

What does the 13 3/4 inch overall length mean when I am lining up holes?

The 13 3/4 inch length gives a 13 inch taper reach so you can drive the 5/16 inch point through thick steel plates.
