Stainless Steel Wedge Bolts

Our Stainless Steel Wedge Bolts are meticulously engineered from European stainless steel to provide climbers with the ultimate blend of strength, stability, and enduring performance.

These are high-quality mechanical wedge bolts with European Technical Certificate ETA-05/0199 for torque-controlled anchors and are the best-priced quality expansion bolt we can source. We batch-test these wedge bolts ourselves to ensure consistent quality.

Wedge bolts work by the expandable clip at the base of the bolt being forced against the wall of the hole. As the bolt is tightened, the bolt’s wedge is pulled into the clip, forcing it to expand outwards, placing pressure on the walls of the drilled hole. When fully tightened, the force of the grip ensures that the bolt is firmly anchored in the hole, resisting any attempt to pull it out again.

Key Features of Stainless Steel Wedge Bolts

• High-Grade Stainless Steel: Crafted from premium European stainless steel, our wedge bolts offer exceptional resistance to general corrosion and wear.
• Superior Anchoring Mechanism: The wedge design ensures that, when installed, the bolt expands to provide a secure and steadfast anchor in the rock, minimising the risk of pull-out and ensuring climber safety.
• Versatile Applications: Perfect for both indoor rigging and outdoor climbing environments, these wedge bolts can be used to set up anchor points, fixed routes, or belay stations.
• Eco-Friendly Durability: The longevity of stainless steel means fewer replacements, resulting in a reduced environmental footprint and long-term value for climbers.

Uses for Stainless Steel Wedge Bolts

• For protection bolts on routes or at anchors (lower offs / bolt belays).
• Rock climbing.
• Canyoning.
• Caving.
• Work at Height.
