Holo-krome 76348 Hex Socket Cap Screw M10x1.50 90mm

Product Description

The HOLO-KROME 76348 is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade service environments. It features an M10 x 1.50 thread profile with a 90 mm (approximately 3.54 inches) length under head and is partially threaded for reliable clamping in through-hole and blind-hole assemblies. Machined from alloy steel to material grade 12.9, this screw delivers exceptional tensile and proof load capacity. The black oxide coating provides a baseline level of corrosion resistance and reduces light reflection in precision assemblies. Licensed trades and mechanical contractors install these screws using a hex key or Allen driver.

This fastener is suited for demanding mechanical assemblies, equipment maintenance, and structural component mounting where high clamp load and dimensional precision are required. The M10 x 1.50 metric thread is common in HVAC equipment frames, pump housings, compressor assemblies, and general industrial machinery. The partial threading ensures the unthreaded shank section acts as a guide and shear-resistant body in close-tolerance bores, making it appropriate for both production assembly and field service repair work.

Key Features

• M10 x 1.50 metric thread for compatibility with standard metric tapped holes
• 90 mm length under head, partially threaded for shear resistance and precision fit
• Grade 12.9 alloy steel construction for maximum tensile strength
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Hex socket drive accepts standard hex keys and socket driver bits
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or service fastener for metric-threaded assemblies requiring an M10 x 1.50 hex socket cap screw to DIN 912 or ISO 4762 specification.

Installation Notes

Installation should be performed by a qualified mechanic or trade technician using a calibrated hex key or torque wrench with the appropriate metric hex bit. De-energize and lock out all equipment before fastener removal or installation. Grade 12.9 fasteners require accurate torque application to achieve proper clamp load without exceeding yield strength — consult the equipment manufacturer torque specification for M10 grade 12.9 fasteners. Do not substitute lower-grade hardware in high-load or safety-critical joints.
