The off-white nylon 6/6 hex bolt has an external hex drive and meets American Society for Testing and Materials ASTM D4066 and D6779 specifications. Nylon 6/6 provides resistance to abrasion, corrosion, and many chemicals and solvents. The material is a strong yet lightweight plastic and is nonconductive. Nylon 6/6 can either absorb or lose moisture, which may alter its dimensions and mechanical properties. The external hex drive has six flat sides that a wrench can grip to turn the screw from the side, enabling use when there is no space above the head for a driver.Cap screws and hex bolts are threaded fasteners with thick hex-shaped heads that can be used with threaded nuts or in areas with limited clearance above the tapped (threaded) hole. Cap screws have slightly different dimensions than hex bolts and have a washer face underneath their unflanged hex head to act as a large bearing surface against the mating material.

When performing a processor upgrade on a 2006/7 Mac Mini, at least 1 of the 4 plastic pins that hold down the heat sink will break.No matter how careful one tries to be, these little parts were not designed to be installed more than once.After some research, I found these little bolts, and the matching nylon #4-40 hex nuts, here on Amazon.They worked perfectly for this purpose, and they are a very inexpensive solution. These bolts are exactly the right length (important because of the tight clearances in a Mac Mini), the right diameter for the heat sink mounting holes, and they are non-conductive.Here is the description (for searching) of the matching hex nuts:Nylon 6/6 Small Pattern Machine Screw Hex Nut, Off-White, #4-40 Thread Size, 1/4" Width Across Flats, 7/64" Thick
