12mm Hex Key Bit Allen Socket – Extended Length for Deep-Set Fasteners

This pack of five 12mm hex key bits delivers the extended reach and precision engagement your shop needs for recessed hex fasteners in tight or deep-set applications. Built from heat-treated S2 steel, these bits resist deformation and maintain sharp engagement through repeated use—essential for high-volume assembly and maintenance operations.

Key Features

• 12mm Hex Socket Size: Matches standard 12mm Allen/hex fasteners; aggressive engagement prevents cam-out
• 75mm Overall Length: Extended reach accommodates deep-set fasteners, countersunk applications, or access through obstructions
• 10mm Hex Drive Shaft: Universal compatibility with standard pneumatic hex drivers, quick-change holders, and manual drive tools
• S2 Tool Steel Construction: Heat-treated for superior hardness and resilience; resists cracking under torque while maintaining flexibility
• Pack of 5: Cost-efficient bulk quantity reduces per-unit cost and ensures immediate replacement availability
• Precision-Machined Hex Profile: Consistent geometry ensures tight fit and eliminates wobble during operation

Why Resellers Choose This Product

Stocking Efficiency: A single SKU covers deep-fastener requirements without holding multiple lengths. The 75mm length bridges the gap between short bits and specialized impact tools, reducing inventory complexity.

Margin Opportunity: Extended-length hex bits command premium pricing in automotive, industrial assembly, and maintenance segments—resellers see 40–60% margins on these professional-grade consumables.

Repeat Purchase Cycle: Hex bits wear through regular use. Mechanics and assembly shops return for replacement packs regularly, building predictable turnover.

Complementary Sales: Bundle with shorter hex bits for complete fastener solutions, or pair with smaller-diameter alternatives for mixed-fastener applications.
