Josh Bowers Weighted Thumbscrew - Heavy Duty Metal Screw for DIY Projects, Home Improvement & Woodworking - Perfect for Furniture Assembly, Cabinet Making & Tool Organization

These turned and knurled brass thumb screws add weight to the front of your machine helping with balance, vibration and needle penetration. Drilled and tapped 8-32 on the edge and through the center to give you two mounting options, they will replace most standard wing nuts. Adding weight to the front of the machine allows the needle to push against that mass as it drives down to the skin, giving you an advantage for more solid, stable lines and allowing you to not have to hold your machine so tight.
