The VINWOX Pin Jaws Set is designed for VINWOX 3.75″ SCK4-3.75 and 4″ SCR4-4 self-centering chucks, aligning with a uniform fixing system across related PSI “C” series.

This VINWOX setup expands turning versatility with a 4-jaw system and 2″ round jaw mounted, including a T-Allen wrench, screw chuck, and a useful adapter, converting between 1″ x 8TPI and 3/4″ x 16TPI. The package aims to cover a broad range of workpieces from bowls to cups. It’s essential to verify spindle compatibility (1″ x 8TPI or 3/4″ x 16TPI) to ensure a correct match. The set promises a strong clamping range for workpieces from 1-1/2″ to 3″ (or 3″ square blocks) with the potential to handle bowls up to 12″ in diameter on compatible machines.
BMWOOD CK-3.75Z-PJ Pin Jaws

They offer both compression and expansion gripping, suitable for gripping inside bowl bases or around small tenons. The jaws stress high clamping force and solid load bearing, making them a strong option for precision work that minimizes surface marring on delicate pieces.
BMWOOD CK-2.75Z-PJ Pin Jaws
The BMWOOD CK-2.75Z-PJ Pin Jaws are targeted for BMWOOD 2.75″ chucks and caution users about cross-brand compatibility. They provide compression and expansion gripping to hold small bowls, egg cups, and goblets, along with a non-marking option for small tenons. As with other pin jaws, a precise match is crucial to avoid poor grip or damage. These jaws emphasize controlled clamping force and reliable hold on fine turnings while maintaining surface integrity.
BMTURNING 4” Self-Centering Chuck Set
The BMTURNING 4” Self-Centering Chuck Set includes dovetail, pin, step, and wide jaws, plus a 5″ flat jaw and a screw chuck. It ships with tightening bars, an Allen wrench, and an adapter that converts 1″ x 8TPI to 3/4″ x 16TPI. The system is compatible with several popular chucks, offering extended gripping options for bowls, spindles, or other turning projects.

It’s designed for BMWOOD’s 2.75″ chucks and is not intended for cross-brand use. The set’s pin jaws, combined with the other jaw types, enable holding bowls or spindles with precision, while the tightening mechanism enhances grip strength for more challenging workpieces.
Buying Guide: Pin Jaws And Chuck Compatibility
- Compatibility matters: Pin jaws are often branded to specific chuck families. Verify spindle thread size (1″ x 8TPI, 3/4″ x 16TPI, etc.) and jaw compatibility before buying to ensure a secure fit and safe turning.
- Grip type: Pin jaws can provide compression and expansion grips. Use compression to hold small tenons or the inside of bases; expansion grips work well for hollow or inside-diameter work. Consider the surface finish requirements to minimize scarring or marking on delicate pieces.
- Piece size and shape: Pin jaws excel with small bowls, cups, goblets, and inside-pocket projects. For larger bowls or non-standard shapes, pair with dovetail or wide jaws to spread grip and reduce pressure points.
- Material and coating: Look for nickel plating or corrosion resistance in jaws intended for green wood or longer tool life. This helps resist moisture and reduces wear during frequent turning sessions.
- Brand ecosystem: Some brands offer interchangeable jaws across multiple chuck models. If you own or plan to expand a set of chucks, choosing a brand with a broad jaw ecosystem can simplify replacements and upgrades.
- Installation and screws: Some pin jaws require specific screws (e.g., M5x12mm, M6x12mm) to attach securely. Confirm the exact screw type included or needed to prevent installation issues.
- Safety and testing: Always test grip with a scrap piece before turning real workpieces. Ensure the chuck is properly mounted and the tailstock is aligned to avoid kickback or imbalance.
The selections above demonstrate a range of pin jaw options and compatible chuck sets from VINWOX, BMWOOD, and BMTURNING. When evaluating these products, prioritize fit to your lathe’s spindle thread, the specific jaw type you need (pin vs dovetail vs flat), and whether the jaw system supports the kinds of projects you typically pursue, from tiny inside-cups to wider bowls. The goal is precise, secure gripping with minimal surface marking and straightforward maintenance for repeated use in American workshops.
