Product Information
Full details
The Spear & Jackson Cross Pein Hammer (4oz) is an essential precision tool designed for professional fitters and hobbyists who require high-accuracy striking in delicate assembly work. Its primary benefit is the combination of a hardened carbon steel head and a balanced hickory handle, which allows for controlled, precise strikes without marring work surfaces. Users should note that as a lightweight 4oz tool, it is specifically engineered for fine assembly tasks rather than heavy-duty demolition or framing projects.

FAQs
Is this hammer suitable for framing?
No, at 4oz, this hammer is designed for light assembly and precision work, not heavy-duty framing.
What does BS876 compliance mean?
It is a British Standard that certifies the hammer head has undergone specific heat treatment to ensure hardness and prevent chipping.
Can I replace the hickory handle?
Yes, hickory handles can be replaced, but ensure you use a compatible size and secure it properly with a metal wedge.
Does the head require oiling?
The head is made of carbon steel; keeping it clean and dry is sufficient to prevent rust.
What is the cross pein end used for?
It is designed for shaping metal, starting small nails, or working in narrow channels where the main striking face won't fit.
Troubleshooting
Head feels loose on the handle
The metal wedge may have loosened. Carefully drive the wedge deeper or replace it to ensure the head is secure.
Handle feels rough or dry
Lightly sand the handle with fine-grit sandpaper and apply a thin coat of wood oil to restore the finish.

Setup, Compatibility & Care
Before your first use, visually inspect the handle for any debris. To maintain the tool:
- Storage: Always store in a dry environment to prevent the hickory handle from swelling or shrinking due to humidity.
- Handle Care: Periodically wipe the wood handle with a light coat of boiled linseed oil to keep the grain hydrated and prevent splintering.
- Head Maintenance: Keep the striking face clean of grease or metal shavings. If the face gathers residue, wipe with a fine-grade scouring pad.
- Safety Check: Before every use, ensure the metal wedge is tight. If you notice any movement between the head and handle, do not use the tool until the handle is properly re-wedged or replaced.
