Solderless Hammer Header for Raspberry Pi

This male hammer header connects to Pi Zero, Bonnet, HAT or pHAT boards without any soldering. It is designed for makers who want a secure pin connection but lack a soldering iron or confidence in their soldering skills. The 50mm by 12mm connector weighs 2.3g and uses 4mm pins. A few hammer taps on a suitable jig lock the header in place.

Best for quick prototyping without heat tools

Suits hobbyists, educators and rapid prototyping workflows where soldering equipment is unavailable or undesirable. Buyers who need a permanent, vibration-proof joint or who are uncomfortable applying mechanical force to a populated PCB should look at traditional soldered headers instead. The supplier notes that plug headers can be trickier to seat than socket versions.

Install with a hammer and a supporting jig

Position the header on the board, place the assembly on a hammer-header jig, then tap the pins gently until fully seated. The most common issue is applying uneven force, which can bend pins or crack the board. Reading the Pimoroni fitting guide beforehand reduces the risk of damage to the Pi Zero, Bonnet, pHAT, HAT or your fingers.

Questions about this item

Do I need a separate hammer-header jig to install these 50mm male headers on a Pi Zero?

The manufacturer highlights note they work best as an add-on to a hammer-header jig, so a jig is recommended for reliable installation.

Can I use these 12mm-tall hammer headers on an existing HAT that already has standard 4mm pins soldered in place?

These headers replace soldered pins; they cannot stack onto pins that are already fixed to the board.

After tapping the 2.3g header into my pHAT, how can I verify every pin made solid contact?

Visually inspect each pin for flush seating, then test GPIO continuity with a multimeter or run a pin-read script on the Pi.
