7/16" Standard Bow Shackle with safety screw pin, type KB, WLL 2.7 tonne, Galvanized Steel Anchor Bow Shackle
Screw Pin Anchor / Bow Shackles
Product Description
On a screw pin bow shackle, a threaded pin is inserted through the ears and tightened down. The screw pin configuration is best for use in applications that are temporary, or require repeated and/or quick connections and disconnections.
The shackles have a large rounded shape that allows them to take loads from many directions without developing significant side load. They are not recommended for permanent or long-term installations.
Bow shackles and anchor shackles are both used interchangeably and refer to a type of shackle with a larger, round “O” shaped bow. A larger bow shape allows these types of shackles to be side loaded or used in multiple sling-leg connections.
Screw pin bow shackles are ideal for use with multiple-leg slings, connecting slings to load rings, and accommodating a wider strap. However, reduction to the WLL must be accounted for when used in a side-loading situation.
Be aware that a live line, such as a sling being used in a choker hitch configuration, can cause the screw pin to be rotated, torqued, or twisted which can cause the pin to unthread itself. Always tighten the pin prior to each lift. When using a screw pin shackle, the screw pin threads shall be fully engaged, tight, and the shoulder should be in contact with the shackle body.
Main features:
- All screw pin shackles are quenched and tempered, with high quality carbon steel shackle bows and alloy steel pins.
- Shackles bows are all hot dip galvanized, screws pins are painted yellow or customized upon request.
- Meets or exceeds all requirements of ASME B30.26-2004 and RR-C-271D.
- Proof Load is 2 times of the Working Load Limit. Minimum Breaking Load is 6 times of the Working Load Limit.
