Discover the Advantages of Vendor Managed Inventory (VMI) and Why Your Business Can Benefit from Its Implementation.

Vendor Managed Inventory (VMI) is a popular inventory management strategy that involves partnering with a supplier to manage the inventory levels of a business. VMI provides numerous benefits to companies, including:

  1. Increased efficiency: VMI allows suppliers to manage a company's inventory levels in real-time, reducing the need for manual inventory tracking and freeing up resources for other tasks.

  2. Improved accuracy: VMI eliminates the risk of human error in inventory management and ensures that the right products are available when needed.

  3. Better inventory management: VMI enables suppliers to monitor inventory levels and adjust their deliveries accordingly, reducing the risk of stockouts or overstocking.

  4. Increased flexibility: VMI allows companies to respond quickly to changes in demand, making it easier to accommodate spikes in sales or unexpected events.

  5. Better communication: VMI fosters better communication between companies and suppliers, leading to improved relationships and increased collaboration.

In conclusion, VMI is a valuable inventory management strategy that can help companies increase efficiency, accuracy, and flexibility. By partnering with suppliers to manage inventory, businesses can focus on their core operations and achieve their goals more effectively.

Coarse Thread Vs Fine Thread Fasteners

Most hardware products(nuts and bolts) you purchase will be Unified National Coarse which is abbreviated (UNC).  This thread pitch is great for projects that require quick assembly. The coarser thread pitch also reduces cross threading incidents.

Unified National Fine Thread abbreviated (UNF) have more threads per inch than course nuts and bolts. UNF products are great for projects that require a high level of precision. These fasteners tend to have a higher tensile strength. Because of the finer thread caution needs to be taken to ensure you do not strip the threads. 


Understanding the Basics of Hex Cap Screws Grades.  

Grade 2, Grade 5, and Grade 8 refers to the quality of the steel used and the manufacturing process of the screw. The grade also determines the amount of stress that can be applied.  This metric is referred to as tensile strength. Grade 2 bolts are inexpensive and great for your basic household uses.  Grade 5 hardware uses a higher quality carbon steel and are case hardened to add more strength. A common application for grade 5 hardware is the automotive industry. Grade 8 hardware carries a typical tensile strength of 150,000PSI. Its strength comes from a full heat treatment vs. case hardening like grade 5.  Grade 8 hardware is used in the most demanding situation and environments.  You can identify each grade by the dashes placed on the head of the screw. See below.


USS VS SAE Washers

SAE washers were developed and the specifications were outline by the Society of Automotive Engineers(SAE) to meet the requirements of automotive manufacturer applications.

USS washers or United States Standard were developed for the engineering requirements of the majority of industrial applications in all fields of manufacturing, maintenance and repair.

SAE washers are have a smaller outside diameter and are thinner than the USS flat washer.

Jobber Bit Vs Mechanic Length Bit. whats Right for you!

A jobber drill bit has a long length compared to its diameter. Jobber bits have roughly a flute length (Twisted Section) 10 times the diameter. For example a .25 in bit will have a flute length of 2.5 inches. Jobber bits are best suited for softer materials.

A mechanics length drill bit is a bit with a shorter flute length and shorter overall length than a standard jobber bit. Having a shorter bit makes it considerably stronger and less prone to breakage, making it a better choice for harder materials.
