Brass insert small head slotted – precision threaded inserts for industrial B2B fastening

Product description and technical specifications

The brass insert with small head and slot is a high-quality thread-forming threaded insert made from solid brass, featuring a metric internal thread from M4 to M8 and a wood-type external thread. It is designed to be screwed directly into a pre-drilled hole in softwood, MDF, chipboard or soft plastics, creating a durable, wear-resistant and reusable metal thread in materials with limited load-bearing capacity. The small head design allows flush mounting with minimal visual impact, while the slotted drive enables precise installation using standard screwdrivers or dedicated insertion tools.

Certain M5 and M6 versions in lengths 6 mm and 8 mm are supplied without a slot, ensuring improved strength in thinner or more delicate materials.

Description

Detailed technical characteristics

• Insert type: brass insert, small head, slotted, with full-length internal thread.
• Metric internal thread sizes: M4, M5, M6, M8, compatible with standard ISO metric screws and bolts.
• Material: solid brass, offering excellent corrosion resistance, good mechanical strength and high wear resistance.
• External thread: wood profile, optimized for high pull-out resistance in soft materials.
• Drive type: slotted head for manual installation; selected short versions without slot for increased structural integrity.
• Recommended installation tools: standard screwdriver for small batches or manual tool 610 / mechanical tool 620 for controlled, axial installation in series production.
• Application materials: softwood, plywood, MDF, particle board, composite panels and soft plastics.

Key advantages for industrial B2B applications

• Reliable and reusable threaded connection, suitable for repeated assembly and disassembly.
• Compact small-head design, ideal for applications with limited space or aesthetic requirements.
• Excellent corrosion resistance, making brass inserts suitable for long-term industrial use.
• Fast and flexible installation, both manual and automated, reducing assembly time and tooling costs.
• Standard metric compatibility, simplifying sourcing, inventory management and engineering design.

Typical industrial applications

• Professional furniture manufacturing and interior fit-out.
• Wood-based panel assemblies in series production.
• OEM assemblies and modular systems requiring serviceable threaded connections.
• Plastic housings and lightweight industrial components where direct threading is not reliable.

Installation guidelines and best practices

1. Pre-drilling: drill a hole according to the recommended diameter for the insert’s outer thread to ensure optimal grip.

2. Insertion: screw the insert straight into the material using the slot or appropriate insertion tool.

3. Final check: ensure the insert is flush and correctly aligned before installing the metric screw to achieve maximum pull-out strength and long-term performance.
