STANLEY screwdriver bit holder SUPERLOK1 120 mm STA62406 — magnetic quick-change adapter for screwdriver bits

STANLEY SUPERLOK1 screwdriver bit holder 120 mm (model STA62406) is a magnetic quick-change adapter designed to hold standard 1/4" hex screwdriver bits securely during manual or powered fastening. With a 120 mm overall length, the bit holder provides extended reach for recessed, deep-set, or hard-to-access fasteners while maintaining stable retention of bits through a magnetic and locking mechanism. The compact diameter and robust construction make it compatible with common cordless drivers, power drills with quick-change chucks, and manual screwdriver handles that accept 1/4" hex bit holders.

Advantages

The SUPERLOK1 bit holder combines magnetic retention with a quick-change locking sleeve to reduce bit wobble and minimize accidental loss during use. Its 120 mm length improves accessibility to confined areas without sacrificing control or torque transfer. The adapter is engineered to fit standard 1/4" hex bits and withstand the repetitive demands of assembly, maintenance, and repair work, providing consistent bit engagement and reliable mechanical connection.

Suitable for

• Reaching recessed screws in furniture, cabinets and fixtures
• Maintenance and repair tasks in automotive or appliance work
• Assembly of flat-pack furniture and construction fittings
• General fastening with cordless drivers and manual handles that accept 1/4" hex bits

Key specifications

• Overall length: 120 mm
• Bit interface: 1/4" hex socket compatible with standard 1/4" hex bits
• Retention: magnetic plus quick-change locking sleeve
• Construction: hardened steel body with corrosion-resistant finish
• Compatibility: designed for use with hand drivers, impact drivers and power drills that accept 1/4" hex bit holders

How to use

Insert a standard 1/4" hex screwdriver bit into the holder until the locking mechanism engages and the bit seats firmly. For quick removal, pull back the locking sleeve and extract the bit. Fit the holder into a compatible driver chuck or manual handle designed for 1/4" hex adapters, then apply steady pressure while turning to engage the fastener. The magnetic retention helps keep the bit in place during positioning, while the locking sleeve secures the bit during higher-torque applications.

Usage recommendations

Use compatible, undamaged 1/4" hex bits and avoid excessive lateral loading to prolong service life; inspect the holder and bits regularly for wear or deformation and replace if locking or magnetic retention weakens.
