Value Collection HC1XX16100-001BX M16 Hex Cap Screw Din 931

Product Description

The VALUE COLLECTION HC1XX16100-001BX is a metric hex head cap screw designed for bolted assemblies requiring corrosion-resistant fasteners. Manufactured from Grade 316 austenitic stainless steel (A4 rating), this fastener delivers strong resistance to chloride environments, chemical exposure, and marine conditions. The screw measures M16 x 2.00 mm thread pitch with a 100 mm length under head and features partial threading per DIN 931 standards. The 24 mm hex drive accepts standard metric wrenches. Tradespeople in plumbing, HVAC, pool equipment, and industrial mechanical work specify A4-grade stainless fasteners where corrosion resistance is a primary requirement.

This fastener is suited for both indoor and outdoor applications where moisture, chemicals, or saltwater exposure is a factor. Typical use cases include mounting brackets, flanged pipe connections, equipment frames, pump housings, and pool or watertreatment system hardware. The partial thread shank provides stronger clamping grip in thick-material joints compared to fully threaded designs. The bright uncoated finish leaves the natural stainless surface intact, which is preferred in food-service, pharmaceutical, and marine installations where coatings may be restricted.

Key Features

• Grade 316 austenitic stainless steel (A4) for superior corrosion resistance in wet and chemical environments
• M16 x 2.00 mm metric thread pitch per DIN 931 standard
• Partially threaded shank for improved clamping in thick-material applications
• 24 mm hex head accepts standard metric combination and socket wrenches
• Bright uncoated finish retains base metal properties — no coating to crack, chip, or contaminate
• 100 mm length under head suits medium-to-deep bolted joint applications

Compatibility

Designed as an OEM-style replacement or new-install metric fastener for equipment and assemblies requiring DIN 931 partially threaded hex cap screws in M16 x 2.00 thread size.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or field technician familiar with metric fastener standards. De-energize or depressurize the system before removing or installing structural fasteners. Apply an anti-seize compound appropriate for stainless steel if the mating nut or tapped hole is also stainless, to prevent galling during torque-up. Torque to the value specified by the equipment manufacturer for M16 Grade A4 fasteners.
