QWORK Brass Top-Post Battery Terminals 8 Pairs (8 Positive + 8 Negative) — Marine-Grade, Corrosion-Resistant Clamps

These QWORK brass top-post battery terminals provide durable electrical contact where dependable power delivery matters. Machined from marine-grade brass, the clamps resist corrosion better than plated steels and maintain conductivity in damp or salty environments. The kit supplies eight positive and eight negative terminals to service multiple batteries or keep spares on hand, with bolt sizes and post diameters sized for common top-post applications.

Will these terminals fit my top-post battery?

Yes — the QWORK terminals are designed to fit all standard top-of-post batteries. The set includes both positive and negative clamps sized to match common post diameters and mounting hardware, so installation is straightforward on most cars, boats, trucks, and equipment.

• Positive pole diameter: 19 mm for standard positive posts
• Negative pole diameter: 17 mm for standard negative posts
• Mounting bolt diameter: 5/16" for secure clamp-down
• Suitable for typical top-post terminal layouts on automotive and marine batteries

How do these terminals hold up in marine or heavy-duty environments?

Manufactured from brass, these terminals offer improved resistance to corrosion, tarnish, and electrochemical degradation compared with many inexpensive alloys. That makes them a practical choice for damp, salty, or vibration-prone settings where reliable conductivity over time is important.

• Marine-grade brass resists rust and pitting in humid or salty air
• Solid construction reduces the risk of loosening under vibration
• Brass maintains low electrical resistance for consistent power delivery
• Durable finish resists wear from repeated installations

How are these terminals installed and maintained?

Installation is simple: place the clamp over the battery post, align the mounting bolt, and tighten to secure the connection. Periodic inspection and light cleaning keep the contact surface conductive; avoid over-tightening and use dielectrics or anti-corrosion spray when storing in harsh environments.

• Fit clamp onto top post, tighten 5/16" bolt to firm contact
• Check torque after initial engine run or first use to ensure seating
• Clean contact surfaces with a brush for long-term conductivity
• Apply anti-corrosion compound for marine or salted-road use

What comes in the kit and what sizes should I expect?

The package contains eight positive and eight negative top-post terminals, providing full sets for multiple batteries or spares for future service. The sizes are selected to match common battery top-post dimensions and mounting hardware used across automotive, marine, and utility applications.

• 8 positive pole terminals (19 mm post diameter)
• 8 negative pole terminals (17 mm post diameter)
• Mounting bolts sized at 5/16" diameter for each clamp
• Enough parts to outfit several batteries or to keep as replacements

Who is this for? These QWORK brass battery terminals are ideal for owners and technicians who need dependable battery connections in cars, boats, RVs, trucks, and construction equipment. Choose this set if you want corrosion-resistant brass clamps sized for standard top-post batteries, bulk quantities for fleet maintenance, or spare connectors for seasonal marine and off-road use.
