Broad Bull Pin with Tether Hole

The Klein Tools 3256TT is a bull pin punch designed for aligning and driving holes in steel. Its 10 inch overall length and 1/4 inch tip size suit structural steel erection and maintenance work. The round shank and plain grip provide direct control during heavy striking. Tether readiness adds drop prevention for elevated tasks.

Sustained Use Performance

Corrosion-resistant construction protects the tool during repeated exposure to job-site moisture and debris. The included striking cap absorbs hammer impact without mushrooming, preserving the shank over long sessions. A 9 inch taper length maintains consistent alignment force across multiple holes. No handguard means the user must maintain proper hand placement for safety.

1-1/16 Inch Tether Hole

The 1/4 inch diameter tether hole is the single specification that determines compatibility with lanyard systems. Workers required to tie off tools at height must verify this dimension matches their tether hardware. Buyers who need a larger attachment point or an integrated handguard will find this model unsuitable. California Proposition 65 warnings apply.

Questions about this item

Does the 10 in bull pin generate noticeable heat or vibration during extended use?

The solid steel construction absorbs impact without significant heat build-up, and the plain grip transmits normal vibration for a hand-held punch.

What striker or hammer is required to drive the 3256TT bull pin?

Any standard hammer or maul with a face large enough to contact the striking cap will work; no specialised driver is needed.

Will the 1/4 in tether hole accept the lanyards already on my older tool belt?

Yes, the 1/4 in diameter hole fits most common tool lanyards and tether clips used on existing belts.
