Ring hammering wrench Rockforce RF-793100 100 mm head, 400 mm length

Ring hammering wrench Rockforce RF-793100 100 mm head, 400 mm length is a hand tool designed for working with ring-end fasteners where additional impact force is required. The wrench combines a closed ring head suitable for gripping bolt or nut profiles with a reinforced shaft and a striking surface for hammer-assisted operations. With a 100 mm ring head and an overall length of 400 mm, this Rockforce wrench provides reach and leverage for access to recessed or obstructed fasteners in mechanical, construction and maintenance settings.

Advantages

The ring-end profile ensures secure engagement with fastener heads, reducing the risk of slippage during torque application or hammer strikes. A dedicated striking surface on the tool allows controlled impact delivery without damaging the wrench or connected fastener when used with appropriate hand strikes or soft hammers. The 400 mm length improves reach and leverage while the construction and materials offer durability for repeated mechanical and on-site use.

Suitable for

• Mechanical assembly and repair where ring-end engagement is necessary
• Construction and structural maintenance requiring impact-assisted loosening or tightening
• Maintenance work in workshops, plants and field service with limited access to fasteners
• Applications where controlled hammer strikes are used to free seized or corroded fasteners

Key specifications

• Ring head diameter: 100 mm
• Overall length: 400 mm
• Tool type: ring hammering wrench (ring-end with striking surface)
• Primary use: impact-assisted tightening and loosening of fasteners
• Typical materials: forged steel construction (manufacturer specification: Rockforce)

How to use

Position the ring head fully over the fastener to ensure full contact with the flats or profile. Apply steady turning force by hand for normal operation; when additional impact is required, use controlled hand strikes or a soft hammer on the designed striking surface to deliver short, measured impacts. Maintain alignment between the wrench and fastener to prevent cam-out or rounding. Inspect the tool and fastener condition before and after impact use to ensure safe operation.

Usage recommendations

Use protective equipment as appropriate (gloves, eye protection) and avoid excessive hammering that could damage the fastener, the tool, or create unsafe conditions. Prefer soft-faced hammers for impact assistance and keep the striking surface clean and free of burrs.
