Panel Latches & Catches · Trade series (compression cam latches) · Application guide Typical applications, the industries that specify compression latches, and how to choose the right size, material and finish for the joint. Compression Latches are used for closing and, where the latch draws, sealing an enclosure door against its gasket. They are manufactured to Trade series (compression cam latches), and selection is driven by the size designation, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Closing and, where the latch draws, sealing an enclosure door against its gasket - **Governing standard:** Trade series (compression cam latches) - **Category:** Panel Latches & Catches Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Compression Latches Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Southco-E3-VISE-ACTION-Compression-Latches.webp) Application guide for Compression Latches to Trade series (compression cam latches). The core duty of the type is closing and, where the latch draws, sealing an enclosure door against its gasket. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below. ## Typical Applications for Compression Latches The most common settings where these are specified: - **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment. - **Maintenance & repair (MRO):** a stocked size for servicing existing plant where the original fastener spec must be matched. - **Fabrication & metalwork:** bench and on-site assembly of steel frames, enclosures and weldments.

Quoting the standard on your order guarantees interchangeable dimensions between suppliers. ## Where Compression Latches Are Not the Right Choice Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure. Custom manufacturing · Made to drawing ## Need a compression latches outside the standard range? The geometry is whatever the drawing says. A machined component has no standard to depart from, so the drawing and the tolerance scheme are the whole specification. Made by stamping or punching. Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Side view and top view, drawn to the dimensions in the table below and redrawn for any size selected. - **Selected by:** panel cutout, grip range and required compression - **Gasket effect:** compresses the door gasket - **Typical application:** outdoor and washdown enclosures ## Dimensions & Specifications (Trade series (compression cam latches)) | Action | Selected by | Gasket effect | Typical application | | --- | --- | --- | --- | | quarter turn with axial draw | panel cutout, grip range and required compression | compresses the door gasket | outdoor and washdown enclosures | | lever-assisted compression | panel cutout and grip range | compresses the door gasket | larger or stiffer doors | | quarter turn with adjustable draw | panel cutout and grip range | compression set on site | enclosures with variable gasket set | Inside the plant ## Manufactured in our own plant This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided. 1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift. 2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g. 3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1. 4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227. ## Frequently Asked Questions ### What are Compression Latches used for?
