When your project demands a material that machines cleanly, conducts reliably, and resists corrosion without surface treatment, finding the right brass stock in an exact cut length can be frustrating. This 8×8×100mm brass flat bar is stocked for makers, machinists, and repair technicians who need a ready-to-use square rod without minimum-order commitments or full-bar waste.
Each piece is a solid brass square rod with a cross-section of 8 mm × 8 mm (approximately 0.315 in × 0.315 in) and a length of 100 mm (approximately 3.94 in). The alloy is a standard free-machining brass, offering a smooth, burr-resistant cut surface suitable for further turning, milling, or filing. Available in packs of 1, 2, or 5 pieces to match your project quantity.
Typical applications include custom electrical bus bars and terminal blocks, decorative hardware inserts and furniture fittings, jig and fixture components in light machine shops, and replacement spacer or standoff stock in industrial repair work. The consistent cross-section makes it well suited for CNC turning and manual lathe operations where tight tolerances are required.
Made from free-machining brass alloy, delivering consistent density and a smooth surface finish that reduces tool wear during cutting, drilling, and threading operations.
Cross-section of 8 mm × 8 mm (0.315 in × 0.315 in) with a 100 mm (3.94 in) length, cut to a consistent size that fits standard collets, vises, and fixturing setups without pre-trimming.
Brass offers moderate electrical conductivity, making this rod suitable for bus bar blanks, terminal connectors, and grounding components in low-voltage electrical assemblies.
Brass forms a stable oxide layer that protects against atmospheric corrosion in indoor and light-outdoor environments, reducing the need for additional surface coatings in most applications.
The free-machining grade allows clean cuts with standard HSS or carbide tooling. The material can also be filed, drilled, tapped, and lightly bent without cracking at room temperature.
Choose 1, 2, or 5 pieces per order to match your exact project needs — reducing waste and letting you scale up for batch production without committing to full-length bar stock.

The bar measures 8 mm × 8 mm in cross-section (approximately 0.315 in × 0.315 in) and 100 mm in length (approximately 3.94 in). These are nominal dimensions; actual cut tolerances are typically within ±0.2 mm for this type of bar stock.
This is a fully solid brass square rod — there is no hollow core. The entire cross-section is solid brass, which makes it suitable for drilling, tapping, and turning operations where wall integrity matters.
Yes. Free-machining brass taps cleanly with standard HSS taps. For an 8 mm square rod, you can typically tap holes from M2 up to M6 depending on placement and wall clearance. Use cutting fluid for best results and longer tap life.
Brass has good resistance to atmospheric corrosion and performs well in indoor and sheltered outdoor environments. In highly humid, marine, or chemically aggressive environments, consider applying a clear lacquer or protective coating to maintain appearance and slow patina development.
Copper offers higher electrical conductivity and is preferred for high-current bus bars. Aluminum is lighter but requires special connectors to prevent galvanic corrosion. Brass sits between the two — it offers adequate conductivity for low-voltage terminals and connectors, with better machinability and corrosion resistance than aluminum in many shop environments.
An 8 mm square cross-section fits most 5C and ER collet blocks with square collet adapters, and clamps securely in standard machine vise jaws. Always verify your specific tooling clearances before beginning a machining operation.
Ordering pre-cut 100 mm lengths eliminates saw setup time, reduces material waste from kerf loss, and avoids the need to handle full-length bar stock in a small shop. The 2-piece and 5-piece packs offer a per-unit cost reduction compared to single-piece orders, making them practical for batch projects or keeping spares on hand.
