Anchor bolt Ebolt JPK-12X300/M5 — expansion fixing dowel 12×300 mm with M5 threaded insert

Ebolt JPK-12X300/M5 is an expansion fixing dowel designed for mechanical anchoring in both solid and hollow base materials. With a 12 mm anchor diameter and a 300 mm overall length that includes an M5 threaded insert, this anchor bolt provides a stable threaded connection point for fixtures, railings, and construction elements where a reliable mechanical joint is required.

Advantages

The expansion principle ensures a secure grip in concrete, solid brick and some hollow masonry when installed according to specifications. The integrated M5 threaded insert allows direct attachment of bolts or threaded rods without additional tapping, simplifying installation and reducing assembly time. Its dimensional combination (12 mm diameter and 300 mm length) offers deep embedment for improved load distribution and pull-out resistance.

Suitable for

• Mounting handrails and balustrades to concrete or brick structures
• Fixing metal frames, brackets and supports in building structures
• Anchoring fixtures and equipment that require an M5 threaded connection
• Applications where a long embedment depth is needed for higher load capacity

Key specifications

• Anchor diameter: 12 mm
• Overall length: 300 mm
• Threaded insert size: M5
• Fixing type: expansion anchor
• Suitable base materials: concrete, solid brick, certain hollow masonry (see installation guidance)

How to use

Drill a hole of the appropriate diameter and depth in the chosen base material, ensuring the hole is clean and free of dust. Insert the expansion anchor until the flange is flush with the fixture or surface. Tighten the mating bolt or threaded rod into the M5 insert to activate the expansion mechanism; follow the manufacturer's recommended torque values to achieve proper expansion without overloading the insert. For hollow masonry use the approved installation technique for expansion anchors in voided substrates or consider additional backing where specified.

Usage recommendations

Confirm the substrate type and load requirements before selection. Use correct drilling equipment and clean the hole thoroughly to ensure full expansion and reliable performance. For safety-critical or high-load applications, consult structural guidelines and follow local building codes to determine spacing, edge distances and embedment depth.
