Stainless steel standard parts thread locking state and solutions

What is called stainless steel screws and nuts thread locking? Locking, also known as biting, refers to the bolt and nut in the fastening process that occurs in the thread bite hold dead phenomenon; it generally occurs in the stainless steel bolt and stainless steel nut between, so also known as stainless steel screw thread locking or stainless steel screw thread biting.

Nylon-Insert Locknuts: These are the most commonly used and are versatile yet economical. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.

Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these locknuts resist rust. However, they won't withstand the harsh chemicals that 316 stainless steel can.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments but won't withstand the harsh chemicals that 316 stainless steel can.

316 Stainless Steel—Our most corrosion-resistant nuts hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals.

Stainless steel standard parts are essential for producing the thread-locking phenomenon, so we must first find the output-locking phenomenon.

What kind of reasons lead to stainless steel standard parts thread locking?

Then， What is the stainless steel screw thread locking phenomenon?

1. Not the correct choice of products in the use of the product should first confirm whether the mechanical properties of the product meet the use of demand (such as the tensile strength of the screw and the safety load of the nut). In addition, the length of the screw should be selected appropriately to tighten the nut after exposure to one or two pitches shall prevail.

2. Rough threads or foreign matter sticking, such as welding points and other metal shavings, interspersed between the threads, often leading to thread locking.

3. Too much force or locking speed is too fast as far as possible to use torque wrenches or socket wrenches; avoid using activity wrenches or electric wrenches. Because electric wrenches often lead to too fast locking speed, the temperature rises rapidly and thread locking.

4. Wrong angle of force application direction Nuts must be screwed perpendicular to the axis of the screw, do not tilt.

5. Unused washers: Washers/retaining rings can prevent overtightening the lock.

Locking or biting often occurs in stainless steel threaded fasteners, aluminum alloys, and titanium alloys threaded fasteners; these metal alloys themselves have anti-corrosion properties and will be damaged in the surface; the metal surface produces a thin layer of oxidation to prevent further corrosion. When the stainless steel fastener threads are locked, the pressure and heat generated between the threads will destroy the oxide layer so that the metal between the threads can cause obstruction or shears and the phenomenon of adhesion. When this phenomenon continues to occur, it will make the stainless steel fastener threads wholly locked and can no longer be removed or continue to lock. Usually, this series of blocking, shearing, adhesion, and lock actions occur in just a few seconds, so the correct understanding of using such fasteners is needed to prevent this phenomenon.

When the stainless steel screws are locked, the pressure and heat generated between the threads will destroy the oxide layer so that the metal between the threads of the occurrence of obstruction or shears, and then the phenomenon of adhesion. When this phenomenon continues to occur, it will make the stainless steel fasteners wholly locked and can no longer be removed or continue to lock. So, how to deal with stainless steel screw locking?

Correct selection of stainless steel fasteners screw products

1. Confirm the mechanical properties of the product before use to meet the use requirements (such as the tensile strength of the bolt and the safety load of the nut);

2. The length of the bolt should be selected appropriately to expose the nut 1-2 tooth spacing after tightening; confirm whether the mechanical properties of the product can meet the use of the requirements before use, such as the tensile strength of the screw and the guaranteed load of the nut. The length of the screw should be selected appropriately to tighten the nut after exposure 1-2 tooth spacing shall prevail.

3, locking high incidence occasions recommended the use of anti-locking nuts. In the direction of force application, the nut must be screwed perpendicular to the axis of the screw.

4. Before use, check whether the threads are rough or have iron filings or dirt between them. These things often lead to locking.

5. Pay attention to the use of the use of methods screwed into the appropriate speed and power, not too fast and too large, as far as possible to use torque wrenches or socket wrenches to avoid the use of activity wrenches or electric wrenches. Too fast speed will make the temperature rise rapidly and lead to locking. The use of washers can effectively prevent the problem of over-tightening the locking.

Reduce friction stainless steel fasteners screw nut thread factor:

1. Keep the threads clean to ensure that the screws and nuts fit smoothly; it is recommended to take the product in a clean container, do not place it randomly;

2. It is recommended to add lubricant before use. Before use is given to the fastener to do lubrication, it is recommended to use butter, molybdenum disulfide, mica, graphite, or talcum powder to do lubrication, the general use of wax dipping treatment to do lubrication anti-thread locking.

Correct use of stainless steel screw nuts installation to reduce the occurrence of thread locking; it is recommended that the proper operation is as follows:

1. When tightening, it should be noted that the direction of wrench force should coincide with the screw axis, do not tilt;

2. In the tightening process, the force should not exceed the safe torque and should be uniform, as far as possible to use torque wrenches or sockets with the use;

3. Too fast locking speed will lead to thread locking; it is recommended not to use electric or pneumatic wrenches;

4. It must be cooled down when used in high-temperature conditions and not be rotated quickly to not cause thread locking due to the rapid rise of temperature (e.g., electric wrench, etc.).
