Category: Slotted Cheese Head Screw DIN84A

Cheese head slotted screws feature cylindrical sides, a flat disc top, and a level bearing surface. Their defining characteristic is the head type, with a height approximately half of the diameter and a slot drive. The term “cheese head” is coined due to the resemblance in shape and proportion to a wheel of cheese.

Vented Screws serve as a conduit for trapped air to exit and be evacuated from the bottom and sides of a blind-tapped hole. This facilitates a quicker and more comprehensive pump-down process for a vacuum system, effectively preventing the occurrence of “virtual leaks.” The trapped air, if not addressed, can pose a risk of contamination to a vacuum system. By enabling faster pump-down and eliminating potential contamination, these vented screws contribute to increased throughput and enhanced yield.
