Thumb Screws Buying Guide

The thumbscrews have specific dimensions, but their look is the same with a flat head for optimal pushing by the thumb, and it has knurled sides and flat vertical heads that are meant to be reused. They are usually applied to those under observation products or appliances or some experiments which are going on temporarily and need fixing. When required, it can be loosened as per the user’s wish. It is usually suggested not to use some critical areas where frequent usage can lose their grip.

Specifications can’t be neglected

The thumbscrews are tiny tools of a shorter length that is ¼ inches – 20 with 0.750 inches of head diameter and .3125 inches of head height. The thread sizes' various measurements may vary as following 6-32, 8-32, 10-32, 5/6-18, 3/6-18. Another kind of length can be M4 × 10mm/0.16 inches × 0.4 inches. These may vary in the quantity as it depends on the buyer to get as much as they want, whether in the pack of 5 pieces, 10, or 15 bits. The buyer should go by the required specifications that will fit their material.

Firm grip over the screws

Thumbscrews required the amount of pressure by humans to be inserted in a device and give it a firm base, but this can only be possible if the flat head of these screws allows the user to operate it without slipping it away from the hands. The knurled surface on these thumb screws eliminates the usage of any kind of tool. It ensures that a user has a firm grip while tightening or loosening it as well as during fastening and unfastening the device without any external pressure. The optimum grip is a necessary function.

Brass construction is best

As these screws are easy to use with the hands, there are chances that any magnetic pull will make it unfastened without any human pressure. This can cause severe accidents or mishaps and can be dangerous for people who have kids and older adults at their house. Safety comes first while using these tiny tools, and that is assured by the brass construction, which is not only corrosion-resistant but also non-magnetic. Free – machining brass or 360 alloy is an excellent choice for these screws because of its advantages.

Use it for decoration

When offering so many features that nobody can deny using them, the thumbscrews also have the upper hand when giving an authentic look. Precision machine finish with a glossy look, these screws make the manufacturer choose them as per the color of the furniture or equipment they are being used. Their face has an elegance that will add charm to the devices on which they are applied. The golden brass color is the most demanded a professional finish. Buyers can also go for silver-colored thumb screws and satisfy their needs.
