Fasteners with a tapered shank (self-tapping screws) chipboard screw & particle board screw Similar to a drywall screw except that it has a thinner shank and provides better resistance to pull-out in particle board, while offset against a lower shear strength. The threads on particle board screws are asymmetrical. concrete screw& Tapcons & masonry screw & confast screw & blue screw & self-tapping screw & Titen A stainless or carbon steel screw for fastening wood, metal, or other materials into concrete or masonry. Concrete screws are commonly blue in color, with or without corrosion coating. They may either have a Phillips flat head or a slotted hex washer head. Heads sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw. deck screw Similar to drywall screw except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread cutting tip for installation into decking materials. They have bugle heads that allows the screw to depress the wood surface without breaking it. double ended screw & dowel screw & hanger bolt Similar to a wood screw but with two pointed ends and no head, used for making hidden joints between two pieces of wood. A hanger bolt has wood screw threads on one end and machine threads on the other. A hanger bolt is used when it is necessary to fasten a metal part to a wood surface. drive screw & hammer drive screw Chiefly used for attaching manufacturers data plates to equipment. Smooth round or mushroom headed with a multi-start thread on the shank, beneath which is reduced diameter shank that acts as a pilot. The screw is fastened by hitting the head with a hammer and is not intended for removal drywall screw Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, however it is a versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the grip diameter. eye screw & screw eye & vine eye Screw with a looped head. Larger ones are sometimes called lag eye screws. Designed to be used as attachment point, particularly for something that is hung from it. A vine eye (in the UK at least) is similar to a screw eye, except that it has a proportionally longer shank and smaller looped head. As the term suggests vine eyes are often used for attaching wire lines across the surface of buildings so that climbing plants can attach themselves.

Automatic nut tapping machine, nut tapping machine, tapping machine Hnt is suitable for hexagon, square, flange and nylon nut. Hnt can reach longer tapping stroke requirement while tapping longer or harder nuts. The operation panel is easy to understand and each spindle can be operated independent. Right or left tapping can be selected, tap life setting and adjust the tapping distance all can set up on the operation panel. Programmable language controller (plc) is used in the machine to monitor and control all tapping actions which can carry some functions including each spindle output counter is independent, operating automatically or manually, adjustable tapping speed, tapping error alarm of each spindle and motor overload alarm. Examination by current meter can detect tapping abnormal, jammed nuts during feeding or empty tapping, which can avoid tools get damage. The replacement of tools is simple and saving time. Magnetic chip filter maintain tapping oil is clean away the chips. Hnt is designed for safety consideration and qualified by ce.
