What are hot melt adhesives?
By Dr. Jody Muelaner Hot melt adhesive (HMA) is a thermoplastic that’s melted, typically using a glue gun, and applied in a molten state. As it cools it solidifies and forms a bond. HMA’s are used to bond paper and card in packaging and bookbinding, wooden furniture, and fabrics. They are used to fix, insulate…
SPC4 Load Indicating System lets users install bolts with accuracy
The integrity of a bolted joint is jeopardized when fasteners lose their tension. This loss of clamping force begins during assembly due to elastic interactions and joint relaxation. Self-loosening continues when the joint is put in service due to vibrations, shock, temperature changes, embedment, etc. The SPC4 joint, available from Valley Forge & Bolt, allows…
What are thumb screws?
By Julie Miller Thumb screws offer a hand-adjustment feature, which allows for simple action to fasten, tighten, loosen, or remove the screws. The main benefit is that no tools are needed, so assembly teams and end-user consumers can adjust the screws with thumb and forefinger alone. Thumb screws are used almost exclusively for the purpose…
Why torque is a critical part of security fasteners
Torque is the essential part of the security of a security fastener. This means that the more weight a screw holds, the more secure it should be and the more pressure will be required to remove it. However, if there is not enough tension when installing security screws, there can be a problem. Although rare,…

What’s the difference between electrical solder and copper plumbing solder?
Written by Miles Budimir Senior Editor, WTWH Media Soldering is a technique used to join together two separate metals using another metal (or metal alloy) with a low melting point. A heat source such as a soldering iron raises the temperature of the two metals to be joined together. When the solder makes contact…
What are industrial seals?
By Dr. Jody Muelaner Industrial seals are used to prevent leakage, hold pressure, and deflect contamination at interfaces between components. Industrial seals are used at static and dynamic interfaces. Examples of static interfaces include the entry point of bolts and screws, and the interface between an engine block and cylinder head. Adhesives and gaskets are…
Four benefits of using eccentric lock washers
Eccentric lock washers are washers that can be combined with commercially available hex nuts to prevent screw loosening. These washers, which are available from NBK, require no special tools for fastening. This means they are as easy to use as spring washers or flat washers. In terms of design, these components consist of a bearing…
What is a prismatic joint?
A prismatic joint is a connection between two objects that allows relative motion along a single axis. Motion that’s perpendicular to this axis (or rotation about any axis) is prevented. This means the joint has one degree of freedom (1-DOF). A prismatic joint is often called a slider — as for example a “crank-slider linkage.”…
