- Forged, heat-treated bull pin increases efficiency by providing a larger striking surface
- Angled head and smooth blending of radii increase strength and reduce the danger of chipping
- Below the head, squared-off shoulders have been forged to provide a surface for applying wrench to loosen wedged bull pins
- Head design also reduces chance of pin slipping from the hand when aligning holes
- Drop-forged, heat-treated
- OSHA 1926.301 (c) specifically states: ''Impact tools, such as drift pins, wedges and chisels, shall be kept free of mushroomed heads.''
