Bosch ITNS516 5/16 Inch Magnetic Nutsetter Impact 5 Pack

Product Description

The ROBERT BOSCH TOOL GROUP ITNS516 is a 5/16-inch magnetic nutsetter engineered specifically for use with high-torque impact drivers. Sold in a pack of 5, each nutsetter measures 5/16 inches by 1-7/8 inches and features an X-Tended Torsion Zone that flexes under load to absorb the rotational shock generated by modern impact drivers. Precision-engineered tips deliver a tighter fit in fastener heads, reducing cam-out and extending service life. Heat-treated construction adds strength throughout the bit body, and a high-visibility sleeve with laser-etched markings keeps size identification fast on the jobsite.

This nutsetter is suited for mechanical, electrical, and general construction tradespeople who run impact drivers daily. The impact-tough rating targets applications where standard nutsetters fail prematurely under high-cycle use. The magnetic retention keeps fasteners seated during placement, which is especially useful in overhead or confined-space installations. The 1-7/8-inch overall length fits standard quick-change chucks without an adapter.

Key Features

• X-Tended Torsion Zone absorbs high-torque shock from impact drivers, extending bit life
• Claimed 10x service life over standard impact bits
• Precision-engineered tips reduce cam-out and improve fastener engagement
• Heat-treated construction for increased strength throughout the bit body
• Magnetic tip retains fasteners during positioning and single-handed driving
• High-visibility sleeve with laser-etched markings for quick size identification

Compatibility

Designed for use with standard 1/4-inch hex quick-change impact drivers. The 5/16-inch drive size is compatible with hex head fasteners and sheet metal screws of the corresponding drive size commonly found in HVAC, electrical, and mechanical assembly work.

Installation Notes

Installation requires a 1/4-inch hex chuck impact driver; no additional adapter is needed for standard quick-change chucks. Confirm the correct drive size matches the fastener before applying torque to avoid fastener or tip damage. Inspect the nutsetter tip for wear periodically, as a worn tip accelerates cam-out under impact loads. Dispose of worn bits per your shop or site waste policy.
