Hex Round Female and Male Threaded Standoff Spacer

Qimao Metal Manufacturer’s Hex Round Female and Male Threaded Standoff Spacer features rounded ends, which is an intentional design choice. The hex body provides wrench flats for secure tightening, while the rounded ends prevent damage to PCBs or enclosure surfaces. Two thread configurations are available. Female versions contain clean internal threads on both ends. Male-female versions have a threaded stud on one end and a female socket on the other. These standoffs are manufactured from hex bar stock or produced through cold heading, followed by roll threading—not cut threading. Rolled threads offer superior strength because the metal is compressed rather than sliced. Finishing options include zinc plating, nickel plating, or plain steel. Standard sizes range from M2 to M8 and 4-40 to 1/4-20. Lengths run from 3mm to 50mm. No unidentified alloys. These are straightforward standoffs that hold boards

Product Parameter (Specification)

Product Feature

· Its body with rounded ends

The hex shape provides wrench flats for secure tightening. Rounded ends prevent gouging into PCBs or scratching enclosure floors. This design delivers sufficient torque without damaging nearby components. Once installed in racks or power supplies, these standoffs hold firmly without harming adjacent hardware.

· Two thread styles in one body

Female standoffs have internal threads on both ends for stacking with screws. Male-female versions feature a threaded stud on one side and a socket on the other. The stud screws directly into a chassis without an extra bolt. Multiple standoffs can be chained for taller stacks. One standoff replaces a screw and spacer combination, shortening the bill of materials.

· Rolled threads, not cut

Cut threads have sharp roots where cracks begin. Rolled threads are formed under pressure, compressing the metal rather than slicing it. The grain flows continuously around the thread form, resulting in stronger threads that resist vibration and stripping. Every thread on these standoffs is rolled.

Application

· PCB mounting – Lifts boards off metal enclosures. Screws pass through board into standoff. Keeps boards secure with airflow underneath.

· Stacking boards –The Hex Round Female and Male Threaded Standoff Spacer female & male screw together end to end. Creates parallel stacks for Raspberry Pi, Arduino, or custom boards.

· Panel spacing – Holds two metal panels apart. Male end into rear panel. Female end accepts front panel bolt. Used in kiosks and medical housings.

Production Installation & Usage:

· Step 1 – Pick the right gender

Use the products Hex Round Female and Male Threaded Standoff Spacer female-female standoffs with screws through both boards. Need to mount one board directly to a metal chassis? Grab a male-female standoff. The threaded stud screws straight into the chassis hole.

· Step 2 – Hand-start everything

Never force a standoff. Spin it onto the screw or into the hole with your fingers first. Cross-threading ruins both the standoff and your board. If it binds early, back it off and try again. Clean threads start easy.

· Step 3 – Tighten with care

Use a wrench on the hex body—not pliers that slip and round the corners. Snug is enough. Over-torquing cracks PCBs or strips threads. For plastic enclosures, stop at finger-tight plus one quarter turn.

· Step 4 – Stacking multiple standoffs

For tall assemblies, screw one male-female standoff into another. Create any height by chaining standard lengths. Check alignment with a ruler before final tightening. Crooked stacks stress boards and break solder joints over time.
