Holo-krome 76304 M10x1.50 Hex Socket Cap Screw 30mm

Product Description

The HOLO-KROME 76304 is a metric hex socket cap screw designed for high-strength mechanical fastening applications. Sized at M10 x 1.50 with a 30 mm length under head and fully threaded shank, this fastener delivers consistent clamping force in tight-clearance assemblies where a hex key drive is required. Manufactured from alloy steel at material grade 12.9, it offers exceptional tensile strength for demanding industrial and mechanical installations. The black oxide coating provides a base level of corrosion resistance and reduces galling during installation. This screw meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards.

This fastener is used across a range of trade and industrial applications including HVAC equipment assembly, mechanical equipment mounting, pump and compressor installation, and general structural fastening. The M10 x 1.50 thread size and hex socket drive make it a common choice for equipment requiring controlled torque and repeatable assembly. It is suitable for use wherever grade 12.9 alloy steel fasteners are specified by equipment manufacturers or engineering drawings.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Fully threaded shank for maximum thread engagement over the full 30 mm length under head
• Hex socket drive accommodates standard hex keys and socket drive tools
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Compliant with ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard metric hex socket cap screw suitable for use in mechanical assemblies, HVAC equipment, and industrial machinery that specifies an M10 x 1.50 grade 12.9 fastener per DIN 912 or ISO 4762.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using the correct hex key or socket drive rated for grade 12.9 fasteners. De-energize and lock out all equipment before fastener service or replacement. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as dry torque values differ from lubricated values. Follow applicable equipment service manuals for torque specifications.
