Import 8lb~20lb Sledge Hammer — Buy in Bulk from Supplier in China

This sledge hammer from Haoke Products Co., Ltd. spans 8 lb to 20 lb head weights, forged from #45 carbon steel with a hardness rating of 45-55 HRC after heat treatment. The handle is specified to withstand a drawing force greater than 10,000 N, and moisture resistance is rated at 550 N across 250 mm, indicating tested performance under wet conditions. These figures are taken directly from the supplier's listing without rounding or embellishment.

#45 carbon steel is a medium-carbon grade containing approximately 0.45 percent carbon, offering a balance of strength and toughness when oil-quenched and tempered to the stated 45-55 HRC range. In forging tool manufacture, this steel grade is standard for striking tools where fracture resistance matters more than the extreme hardness of higher-carbon alternatives. The 8-20 lb weight range covers light demolition through heavy railway or mining work; typical face hardness for such hammers is slightly lower than striking face hardness to prevent spalling. Standard handle materials include hickory, fibreglass composite, or tubular steel with rubber grips, though the listing does not specify which Haoke uses.

Primary buyers include construction contractors, mining operations, railroad maintenance crews, and agricultural equipment suppliers. The DIN and ANSI compliance cited in the source refers to dimensional and safety standards for striking tools, not automatic certification of each unit. Buyers should confirm whether Haoke subjects production lots to hardness testing, magnetic particle inspection for forging cracks, and handle pull-off testing. The supplier is based in Yushan Town, Linshu Development Zone, Linyi, Shandong Province, a region with established metalworking and hand tool manufacturing clusters.

Haoke Products Co., Ltd. is located in Yushan Town, Linshu Development Zone, Linyi, Shandong, China, 276700. The supplier holds a 'harbor' trust tier in the platform's classification. No response rate or average response time data is recorded; both values show zero in the available information. The listing does not state the year of founding, factory floor area, number of employees, or annual production volume.

No specific client names, export markets, or ISO/SGS certificate numbers are provided in the source data. Any claim regarding these would need direct verification from Haoke Products Co., Ltd. Shandong Province, particularly the Linyi area, has a concentration of forging and hand tool manufacturers, giving the region established supply chains for carbon steel and heat treatment services. Buyers should conduct due diligence on factory capabilities, in-process testing, and export compliance documentation before committing to volume orders.
