Product Details

Captive screws:

Captive screws, also known as spring panel screws, captive screws can be riveted on the iron plate, and can freely screw in and screw out. And the whole piece can be firmly mounted on the panel without detaching from the panel, which is also referred to as not detaching screws. The outer circle of the hand-screw sleeve is generally pressed with straight teeth to facilitate hand-screw or manual tightening, it is also called hand-screw screws or hand-screw screws. The panel spring screw and the undetachable screw are composed of the following accessories.

The panel screws are designed to use a minimum of parts, eliminating the risk of hardware loosening that could come off and damage the internal components. These panel screw sets

Pieces are ideal for connecting metal panels or other thin material components to provide the required application interfaces.

Screw, fastening the other end of the chassis plate by it, the general material to stainless steel-based, head-shaped cross or a slot to facilitate tool tightening, usually used for +-slot.
Hand-wrung gloves; generally there will be a straight pattern, the material is usually aluminum, sometimes according to the need for aluminum oxidation to black.
Press-riveted sleeve, riveted to the panel on it.
Spring: to facilitate the expansion and retraction of the screw and keep the whole component. After each part is produced, it is assembled into an integral whole, and the hand-twisted part is extruded so that the hand-twisted part and the press-riveting part are inlaid together by a spring to form a complete spring-plate screw.
Spring screws can be used to install a PCB board, which only takes up a small space. The riveting sleeve of the hand-tightening screw has an embossing tooth, which is pressed into the hole of the chassis or the thin plate to form an exposed spring screw. The other end is screwed with the hand because the spring is fixed in the other end, and the screw enters and exits relative to the other end of the thin plate, this product solves the problem of frequent screw removal and is extremely convenient to use.
