Bolt and Torque Recommendations for EVE 280AH LiFePo4 cells
1) never coat the threads, it acts like a grease and will skew pressure/force readings and possibly lead to stripping the soft aluminium. 2) you can buy Stainless screws that fit from Homedepot, while there, get matching stainless washers. Take your original screw to make sure you match thread etc perfectly.

components and the screw head become tight. The torque rate can vary considerably for the same diameter of screw. A short screw clamping plain metal components reaches the rated torque in only a fraction of a turn of the screw. This type of joint is defined as a "hard joint". A joint with a long screw that has to compress soft components such

Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential

Stud Welding Methods | STANLEY® Engineered Fastening
With drawn arc stud welding, the operator uses a weld tool, or gun, to place the stud against the base metal. When triggered, an electric solenoid in the gun lifts the stud to a preset height off the base metal. The drawn arc melts the base of the stud and the base metal, creating a molten pool. The gun then forces the stud down into the molten
