Ultra-Fine-Thread Plastic-Head Thumb Screws
Fine threads give you precise control. They have a ball bearing tip that adjusts to angled surfaces and minimizes damage from surface contact. They have a lightweight and nonconductive plastic head and chemical-resistant 18-8 stainless steel threads. The head is knurled for slip-resistant controlled adjustment. Length is measured from under the head.
Optional threaded inserts can be used to install these thumb screws into existing holes.
