Product Introduction and Usage of Carpenter Cramp
adsfad
Product Name: Carpenter Cramp
Product Introduction:
Carpenter Cramp is a specialized metal fastener featuring a unique barbed shank design. Originally developed for heavy-duty woodworking applications, its sharp helical barbs provide exceptional grip strength, preventing backward movement once driven into materials. Manufactured from hardened steel, stainless steel, or galvanized iron, it combines durability with weather resistance for both indoor and outdoor use.
Key Features:
Helical Barb Technology: Spiral barbs create a screw-like locking effect, eliminating nail creep in dynamic loads.
Woodworker-Centric Design: Optimized for timber-to-timber and timber-to-masonry bonding.
Anti-Corrosion Treatment: Zinc-plated or stainless steel variants resist rust in humid environments.
Impact-Ready: Compatible with pneumatic nail guns for high-speed installation.
Primary Applications:
Timber Framing: Securing beams, joists, and trusses in log cabins/post-and-beam structures.
Decking & Flooring: Permanent fastening of hardwood planks with reduced surface splitting.
Formwork Assembly: Locking concrete molds without weld points.
Heritage Restoration: Replacing traditional joinery in antique furniture preservation.
Usage Guidelines:
Pre-drill pilot holes in dense hardwoods (e.g., oak, teak)
Drive at 15°-30° angle for maximum withdrawal resistance
Pair with epoxy adhesives for seismic-resistant structures
Technical Specifications:
Length: 1" (25mm) to 6" (150mm)
Shank Diameter: 10-12 gauge (3.25mm-4.0mm)
Head Type: Flat countersunk / Round washer head
Compliance: ANSI/NFPA 70E (sparking resistance for electrical safety)
Note: The term "Carpenter Cramp" reflects its dual function as both a fastener (nail) and temporary clamping aid during assembly. Contact us for custom barb patterns or length-to-diameter ratios.
