Designed for professional demolition, stake driving, and rescue operations, it offers superior vibration absorption and meets rigorous BS 876, SANS 387, and ANSI standards, ensuring unmatched durability and performance in demanding environments. ## Description Groz 34524 Indestructible Handle Sledge Hammer with 20-Pound Head and 36-Inch Handle features an indestructible handle made with six spring steel bars, each measuring 7.1mm in diameter, which run all the way through the full length of the handle to resist overstrike without breaking. The head will not become loose, as steel bars are locked with a steel plate on top of the hammer head, ensuring the head will never get dislodged. Forged from special steel, the head is induction-case hardened to 52 - 56 HRC for extended life. The ergonomic, vulcanized rubber-grip handle absorbs impact and vibration, reducing user fatigue. Made from a special grade of ozone-resistant rubber for use in tough outside environments, the textured non-slip grip helps guard against user error. Great for driving in stakes, heavy demolition work in construction like fracturing stone and concrete, driving fence posts, rebar work and bending or shaping metal. Also great for police fire and rescue applications as well as in railroad work. Sledge Hammers are used, abused & misused day-in & day-out - for heavy demolition work in construction environments, railroad, underground mining etc. These are rough use tools that take a lot of beating. No matter how much care you take, incorrectly hitting the hammer on the handle instead of the head cannot be avoided. Conventional Wooden Handle & Fiber Glass handles fall apart not just when overstriked, but in a few hundred strikes even when used with full care. The Groz INDESTRUCTIBLE hammer won't stop no matter what you do to it. Paying a little extra compared to conventional hammers for a lifetime of use works out to a fraction of the cost than what you would spend buying multiple units of conventional hammers for the same Job. Groz Indestructible Handle Hammers meet ANSI specifications "Hand Tools - Heavy Striking Tools Safety Requirements", as well as BS 876 specifications for material, hardness and performance. ## Features - Indestructible handle made with Four spring steel bars which run the full length of the handle - Bars are locked with a steel locking plate ensuring the hammer never gets dislodged - Hi-visibility head allows for easy identification on a jobsite - Vulcanized rubber grip handle absorbs vibration and reduces fatigue - Perfect for driving stakes, metal forming, setting bolts and minor demolition work ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BHKX54FL | | Best Sellers Rank | #168,354 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #50 in Sledgehammers | | Brand | Groz | | Brand Name | Groz | | Color | 52 Hrc Head | | Customer Reviews | 5.0 out of 5 stars 1 Review | | Global Trade Identification Number | 00816139018614 | | Grip Type | Ergonomic, Non-slip | | Handle Material | Metal,Steel | | Head Material | Alloy Steel | | Head Style | Flat | | Included Components | sledge hammer | | Item Type Name | Unbreakable sledge hammer | | Item Weight | 22 pounds | | Manufacturer | Groz | | Manufacturer Part Number | 34524 | | Model Number | 34524 | | Number of Items | 1 | | Number of Packs | 1 | | Style Name | 36" Handle | | UPC | 816139018614 | | Unit Count | 1 Count | ## Product Details - **Brand:** Groz - **Color:** 52 Hrc Head - **Handle Material:** Metal,Steel - **Head Material:** Alloy Steel - **Item Weight:** 22 pounds ## Images ![Groz Heavy Duty 20lb Sledge Hammer with 36-Inch Indestructible Handle | Hard Face Steel Head 52 HRC | Steel Locking Plate | Hi-Visibility Head | Vulcanized Rubber Handle (34524), 20 lb Head - Image 1](https://m.media-amazon.com/images/I/51FaXp64DKL.jpg) ![Groz Heavy Duty 20lb Sledge Hammer with 36-Inch Indestructible Handle | Hard Face Steel Head 52 HRC | Steel Locking Plate | Hi-Visibility Head | Vulcanized Rubber Handle (34524), 20 lb Head - Image 2](https://m.media-amazon.com/images/I/51gjg7iayUL.jpg) ![Groz Heavy Duty 20lb Sledge Hammer with 36-Inch Indestructible Handle | Hard Face Steel Head 52 HRC | Steel Locking Plate | Hi-Visibility Head | Vulcanized Rubber Handle (34524), 20 lb Head - Image 3](https://m.media-amazon.com/images/I/71Ec3m1aSSL.jpg) ![Groz Heavy Duty 20lb Sledge Hammer with 36-Inch Indestructible Handle | Hard Face Steel Head 52 HRC | Steel Locking Plate | Hi-Visibility Head | Vulcanized Rubber Handle (34524), 20 lb Head - Image 4](https://m.media-amazon.com/images/I/51LW1lReCWL.jpg) ![Groz Heavy Duty 20lb Sledge Hammer with 36-Inch Indestructible Handle | Hard Face Steel Head 52 HRC | Steel Locking Plate | Hi-Visibility Head | Vulcanized Rubber Handle (34524), 20 lb Head - Image 5](https://m.media-amazon.com/images/I/71hvorqOW8L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Frequently Bought Together - Groz 34517 36" Indestructible Sledge Hammer, 8 lb - Groz 34550 12" Indestructible Striking Hammer, 2.5 lb, Soft 30 HRC - Klein Tools 5416TFR Tool Bag, Flame Resistant Canvas Bag for Bolt Storage with Double Reinforced Bottom and Tunnel Connect, 5 x 10 x 9-Inch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/14083885-groz-heavy-duty-20lb-sledge-hammer-with-36-inch-indestructible](https://www.desertcart.jp/products/14083885-groz-heavy-duty-20lb-sledge-hammer-with-36-inch-indestructible) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-18*
