Spanner wrench Proline 36927, length 178 mm, single piece

Proline 36927 is a forged spanner wrench with a total length of 178 mm, supplied as a single piece. Made from chromium-molybdenum steel and finished with a phosphate coating, this spanner wrench features a reinforced slogging head for increased durability. Its compact size and solid construction make it suitable for turning and tightening nuts and fittings within the jaw capacity in confined spaces.

Advantages

The forged construction and chromium-molybdenum steel composition provide high strength and resistance to deformation under load. A phosphated surface treatment improves corrosion resistance and reduces surface friction. The reinforced slogging head increases impact resistance when used with light hammering during loosening or tightening operations. Compact 178 mm length offers better access in tight areas compared with longer wrenches, while the single-piece design ensures consistent alignment and durability.

Suitable for

• Automotive repair and maintenance in restricted access areas
• Household plumbing tasks involving nuts and fittings
• General workshop and mechanical assembly or disassembly

Key specifications

• Total length: 178 mm
• Material: chromium-molybdenum steel (chromium-molybdenum)
• Construction: forged, single-piece design
• Surface finish: phosphated
• Head type: reinforced slogging head for impact resistance

How to use

Select the spanner wrench according to the nut or fitting size that matches the jaw capacity. Position the wrench fully over the flats of the fastener to ensure even load distribution. Apply steady manual force in the required direction; if light impact is needed for loosening, use controlled blows to the slogging head with an appropriate hammer. Avoid excessive side loading or prying to prevent damage to the wrench or fastener.

Usage recommendations

Inspect the tool before use for signs of wear, cracks or significant corrosion. Use the spanner wrench within its mechanical limits and avoid applying torque beyond what the fastener or tool can safely handle. Store in a dry place to preserve the phosphated finish and periodically clean and lightly lubricate contact surfaces to maintain performance.
