These are black Zinc coated stainless steel pass-thru posts with a clutch feature on the under lip of the head. They are used for mounting sheath and holster attachments. Because they are pass-through, almost any 8-32 screw can be used. Some users also like to reverse their mountings to make the attachment more secure. These will fit any screw with an 8-32 thread. The clutch feature creates a non-slip effect. This is needed in situations were the tightness of the assembly is important.
