Description
Overview:
The Adjustable Tap Socket M4 - M14 is a compact driver that lets you turn threading taps, reamers and screw extractors using standard 3/8" (9.5 mm) drive hand tools. Built from hardened steel with a corrosion‐resistant finish, it grips square shanks securely while keeping a low profile for access in tight spaces. The stepped collet accepts square shanks from 5 mm to 8 mm across flats, covering common tap sizes from M4 to M14 as well as many equivalent imperial sizes. Use it with a ratchet, T‐bar, breaker bar, or torque wrench for controlled, accurate threading and extraction work. It is well suited to workshop, site and garage use where reliable, repeatable results and easy handling are needed.
Key Features:
- Adjustable to fit M4-M14 thread taps for broad coverage in one tool
- Designed for 3/8" (9.5 mm) drive socketry; works with ratchets, T‐handles and extensions
- Accepts square shanks 5-8 mm across flats, including many reamers and screw extractors
- Stepped collet jaws for positive, centred grip on a wide range of square sizes
- Hardened steel body with corrosion‐resistant finish for long service life
- Knurled outer sleeve for improved hand grip during set‐up and alignment
- Low‐profile form for working close to surfaces and inside confined areas
- Suitable for right‐hand and left‐hand taps when used with the appropriate driver
- Helps keep taps square to the workpiece for cleaner, more accurate threads
- Simple to fit and remove; easy to clean and maintain in everyday workshop environments
Typical Applications:
Cutting new threads and chasing damaged threads in ferrous and non‐ferrous metals, plastics and composites. General repair and maintenance on machinery, engines, gearboxes, and equipment. Fabrication and assembly tasks in automotive, agricultural, construction and garden machinery. Removing broken bolts and studs with square‐shank extractors. Precision work where controlled torque via a 3/8" (9.5 mm) drive is preferred.
