Adjustable Leveling Foot

What is a high strength screw? Since high-strength screws are different from ordinary screws, their process flow will also be unique. It is divided into three parts. The first step is the pretreatment process, which includes pre electroplating accuracy and appearance inspection, manual degreasing, soaking degreasing, pickling, electric activation and other processes. Then there is the electroless nickel plating process, and finally the post-treatment process, including

m12/m16/m20 fixed adjustable leveling foot KTF-M-12 Large hexagon high strength bolt The raw materials for the production of large hexagon high-strength bolts are all high-quality steel produced by domestic well-known large-scale steel manufacturers that meet the provisions of relevant material standards. They are precision manufactured by international advanced professional production equipment and undergo professional heat treatment processing by advanced heat treatment

Inspection method of thread plug gauge If the measured thread can be screwed through the thread through gauge and not completely screwed through the thread stop gauge The over thread non-return gauge is only allowed to screw in two sections with the measured thread, and the screw in amount shall not exceed two threads The pitch indicates that the pitch diameter of the measured thread does not exceed the pitch diameter of its maximum solid profile If the single pitch diameter

How to deal with the corrosion of screws Screw, as a metal product, is bound to face the problem of rust. The installed screws are rusty, beautiful, and even involve safety problems. So how to deal with this problem? First of all, for the environment, it is impossible to keep dry all the time, especially in some humid areas. Then there is the material of the metal itself. Compared with iron, stainless steel is indeed more durable. In this way, all stainless steel should be

Application method of thread ring gauge Usage of thread ring gauge: screw two ring gauges onto the external thread to be tested in random order 1. The non-stop gauge passes through the small pitch diameter, and the product is unqualified. 2. The general gauge can not be screwed. The pitch diameter of the thread is large, and the product is unqualified. 3. the go gauge can rotate freely at any position of the thread. The non-stop gauge can be screwed for one to two or three

Causes and solutions of screw slip As a fastener, the most important thing is to "tighten" and "fix", and the thread is the most direct and important reason affecting the fastening of screws. Screw slippage is not uncommon. What is the reason for slippage? KT castors classify them into five types: 1. The tooth outer diameter is too small and the screw pit is not filled laterally, resulting in sliding teeth; There are many solutions to these five reasons. For example, you can

on-slipping adjustable leveling feet m6 Threaded Glide Supporting foot KTF-P-20 Thread knowledge 1. 55 ° cylindrical pipe thread 55 ° cylindrical pipe thread comes from Inch series, but it is widely used in metric and inch countries. It is used for the connection between pipe joints and pipes for conveying fluid and installing wires. However, the codes of countries are different, which can be compared in the following table. Country: China Japan UK France Germany ISO Code g,

Analysis of machining error The so-called error refers to the difference between the real value and the theoretical value. For machining production and manufacturing, usually the theoretical value obtained through model calculation or drawing design is the design value after optimization and idealization. In the actual processing process, this idealized theoretical value is impossible to achieve, because the theoretical value does not consider the inherent errors of machining

What standard should be adopted for the specification of anchor bolts of steel structure 1. The specification of anchor bolt of steel structure is Q235B. The steel column base bolt cannot be used for shear, and the shear force is borne by the shear key. 2. It consists of Q + number + qualitygrade symbol + deoxidation method symbol. Its steel grade is marked with "Q", which represents theyield point of steel. The following numbers represent the yield point value, and the unit

Analyze the tensile capacity of anchor bolts The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself. The allowable tensile bearing capacity in design is the cross-sectional area multiplied by the design value of tensile strength (140MPa). When the foundation screw and mechanical component are installed on the concrete foundation, the J-shaped and L-shaped ends of the screw are embedded in the concrete. The function of fastening machines, etc
